Genealogists measure closeness two ways. The degree of kinship counts steps: civil law adds the steps up and down (your first cousin once removed = 3 + 2 = 5th degree), while canon law takes the longer side (3rd degree). The coefficient of relationship (kinship coefficient) is the expected fraction of shared DNA — 50% for a parent, 12.5% for a first cousin, 3.13% for a second cousin. Every answer above shows both, so this page doubles as a degree of kinship calculator and kinship coefficient calculator, not just a name lookup.
What is my cousin's daughter to me?+
She is your first cousin once removed. Your parent and her grandparent are siblings, so you share grandparents. The "once removed" means you are one generation apart: you are the older generation, she is the younger one. You share about 6.25% of your DNA.
What is my mom's cousin to me?+
Your mom's cousin is your first cousin once removed. Your grandparent and your mom's cousin's parent are siblings, which makes your mom and her cousin first cousins — and you one generation below that. You share about 6.25% of your DNA. From her side, you are her first cousin once removed too.
What is my dad's cousin to me?+
Your dad's cousin is your first cousin once removed. The logic is the same as your mom's cousin: your dad and his cousin are first cousins, so you sit one generation below their relationship. You share about 6.25% of your DNA.
What is my parent's first cousin to me?+
Your parent's first cousin is your first cousin once removed — this is the textbook example of the term. Your grandparent and their parent are siblings. You share about 6.25% of your DNA, and "removed" simply counts the one-generation gap between you.
What is my mom's second cousin to me?+
Your mom's second cousin is your second cousin once removed. Your mom and her second cousin share great-grandparents; you are one generation further down, sharing about 1.56% of your DNA. The "second" counts the cousin degree, the "once removed" counts the generation gap.
What is my aunt's cousin to me?+
Your aunt's cousin is your first cousin once removed. Your aunt and her cousin are first cousins (they share grandparents — your great-grandparents), and you are one generation below that pair. You share about 6.25% of your DNA.
What is my uncle's cousin to me?+
Your uncle's cousin is your first cousin once removed, for the same reason as your aunt's cousin: your uncle and his cousin are first cousins, putting you one generation apart from their relationship. You share about 6.25% of your DNA.
What is my grandma's cousin to me?+
Your grandma's cousin is your first cousin twice removed. Your grandma and her cousin are first cousins (they share grandparents — your great-great-grandparents), and you are two generations below them. You share about 3.13% of your DNA.
What is my grandfather's cousin to me?+
Your grandfather's cousin is your first cousin twice removed. Your grandpa and his cousin share grandparents, and you sit two generations below their generation. You share about 3.13% of your DNA.
What is my cousin's son to me?+
He is your first cousin once removed — the mirror image of "my cousin's daughter." Your parent and his grandparent are siblings, so you share grandparents, with one generation between you. You share about 6.25% of your DNA.
What is my cousin's child to me?+
Your cousin's child is your first cousin once removed, regardless of whether the child is a son or daughter. You share grandparents (your parent and the child's grandparent are siblings), and the "once removed" marks the one-generation gap. Shared DNA is about 6.25%.
What is my cousin's grandchild to me?+
Your cousin's grandchild is your first cousin twice removed. The cousin degree stays "first" (you still connect through shared grandparents), but the generation gap grows to two. You share about 3.13% of your DNA.
What is my cousin's wife to me?+
Your cousin's wife is your cousin-in-law — related to you by marriage, not by blood. You share no DNA through this connection (barring any separate blood tie). Genealogists still record the relationship because it matters for family records, but it carries no coefficient of relationship.
What is my cousin's husband to me?+
Your cousin's husband is your cousin-in-law, related by marriage only. Like your cousin's wife, he shares no DNA with you through this link. If you need a blood term for forms or DNA matching, there isn't one — that's normal.
What is my mother's first cousin to me?+
Your mother's first cousin is your first cousin once removed. Your grandparent and their parent are siblings, making your mother and her cousin first cousins. You are one generation below, sharing about 6.25% of your DNA.
What is my father's first cousin to me?+
Your father's first cousin is your first cousin once removed — the classic case. Your grandparent and their parent are siblings. You share about 6.25% of your DNA, and you are one generation apart.
What is my second cousin to me?+
A second cousin shares your great-grandparents: your grandparent and their grandparent are siblings. Second cousins are in the same generation as you and share about 3.13% of their DNA. Many people discover second cousins through DNA tests — they are close enough to match, distant enough to be a surprise.
What is my third cousin to me?+
A third cousin shares your great-great-grandparents: your great-grandparent and their great-grandparent are siblings. You share about 0.78% of your DNA — small, but still detectable on consumer DNA tests, which is why third cousins show up as matches.
What does first cousin once removed mean?+
"First cousin" means you share grandparents (your parent and their parent are siblings). "Once removed" means the two of you are one generation apart. So a first cousin once removed is either your parent's first cousin or your first cousin's child — the same term covers both directions.
What is my great aunt's son to me?+
Your great aunt's son is your first cousin once removed. Your great aunt is your grandparent's sister, so her child is your parent's first cousin — one generation above you. You share about 6.25% of your DNA.
What is my great uncle's daughter to me?+
Your great uncle's daughter is your first cousin once removed. Your great uncle is your grandparent's brother, making his daughter your parent's first cousin. You share about 6.25% of your DNA.
What is my mom's aunt to me?+
Your mom's aunt is your great-aunt (also called grandaunt). She is your grandparent's sister, one generation above your mom and two above you. You share about 12.5% of your DNA.
What is my dad's uncle to me?+
Your dad's uncle is your great-uncle (also called granduncle). He is your grandparent's brother. You share about 12.5% of your DNA, and he is two generations above you.

What is my half brother's cousin to me?+
It depends on which side the cousin comes from. If the cousin is related through the parent you share with your half-brother, that cousin is also your first cousin (about 6.25% shared DNA). If the cousin comes through your half-brother's other parent, there is no blood relationship to you at all. Ask which parent connects them — that decides the answer.
What is my cousin's cousin to me?+
There is no single answer — it could be your cousin, your sibling, or no relation at all. Your cousin's other cousin might be related through the cousin's other parent (no tie to you), or it might be your own sibling or cousin. This is one of the genuinely ambiguous phrases in genealogy.
What is my wife's cousin to me?+
Your wife's cousin is related to you by marriage, not blood — there is no standard blood term for it. Socially, many families just say "my wife's cousin." You share no DNA through this connection.
What is my husband's first cousin to me?+
Your husband's first cousin is connected to you by marriage only, with no blood relationship and no shared DNA. Like all in-law connections, the term describes the social link, not a genetic one.
What is my brother's wife's cousin to me?+
Your brother's wife's cousin is related to you only through two marriage links (your brother's marriage, then the cousin's blood tie to your sister-in-law). There is no blood relationship and no standard English term — "my sister-in-law's cousin" is how everyone says it.
What is my cousin's daughter's child to me?+
Your cousin's daughter's child is your first cousin twice removed. Your cousin's daughter is your first cousin once removed; her child pushes the generation gap to two while the cousin degree stays first. You share about 3.13% of your DNA.

What is my dad's cousin's son to me?+
Your dad's cousin's son is your second cousin — the male counterpart of "my mom's cousin's daughter." You share great-grandparents and about 3.13% of your DNA, and you are in the same generation.
What is my grandpa's brother's son to me?+
Your grandpa's brother's son is your first cousin once removed. Your grandpa's brother is your great-uncle, and his son is your parent's first cousin — one generation above you. You share about 6.25% of your DNA.
What is my sister's cousin to me?+
Usually, your sister's cousin is also your cousin — most cousins are shared between siblings. The ambiguous case is a cousin related only through one parent in a blended family, or your sister's cousin-in-law through a partner. In the standard case, the answer is simply "your cousin too."
What relation is my cousin to me?+
A plain "cousin" almost always means first cousin: your parent and their parent are siblings, and you share grandparents. First cousins are in the same generation and share about 12.5% of their DNA. If someone says just "cousin" without a number, first cousin is the safe assumption.
What is my parents' second cousin to me?+
Your parents' second cousin is your second cousin once removed. Your parent and their second cousin share great-grandparents; you are one generation below that pair. You share about 1.56% of your DNA.
What is my uncle's second cousin to me?+

What is my cousin's kid to me?+
Your cousin's kid is your first cousin once removed — "kid" works exactly like "child," "son," or "daughter" here. You share grandparents with a one-generation gap, and about 6.25% of your DNA.
What is my first cousin's child to me?+
Your first cousin's child is your first cousin once removed. This is the downward direction of the term (the upward direction is your parent's first cousin). You share about 6.25% of your DNA.
How much DNA do I share with my first cousin?+
Theoretically 12.5% — first cousins share a pair of grandparents, giving a coefficient of relationship of 1/8. In centimorgans that is roughly 930 cM out of about 7,400. Real inheritance varies because of random recombination: tested first cousins typically share between 600 and 1,200 cM, averaging around 850–900 cM.
Relationships here follow standard genealogy (blood kinship). Marriage connections are labeled honestly as by marriage with no shared DNA. "Half" relatives share one parent's line; "step" relatives are connected by marriage only. Shared-DNA figures are theoretical coefficients of relationship — real inheritance varies a little because of recombination.
