what does first cousin once removed mean

A “first cousin once removed” is a first cousin who is one generation away from you.

Put simply, it can mean either:

  • Your first cousin’s child (down one generation).
  • Your parent’s first cousin (up one generation).

Quick Scoop: What does “first cousin once removed” mean?

Basic definition

  • “First cousin” = you share a set of grandparents; your parents are siblings.
  • “Once removed” = one generation apart from you (either older or younger).

So, “first cousin once removed” = someone who is a first cousin in your family line, but not in your generation.

Two main situations

  1. Your cousin’s child
    • Your first cousin’s son or daughter is your first cousin once removed.
 * You are also _their_ first cousin once removed (the relationship name is the same in both directions).
  1. Your parent’s cousin
    • Your mom’s or dad’s first cousin is also your first cousin once removed.
 * You are one generation below them, but still in that “first cousin” line.

Quick mental trick

  • First, ask: “What cousin level?”
    • Shared grandparents → first cousins.
  • Then ask: “Same generation?”
    • Same generation → just “first cousin.”
    • One generation different → “first cousin once removed.”

Example:

Your grandma and someone else’s grandma are sisters → their grandchild is your first cousin.

If that cousin has a child, that child is your first cousin once removed.

Mini FAQ

  • Is a first cousin once removed the same as a second cousin?
    No. Second cousins share great‑grandparents, while first cousins (and their “removed” versions) share grandparents.
  • Why “removed”?
    “Removed” is just genealogy jargon for “different generation.” Once removed = one generation; twice removed = two generations.

TL;DR:
A first cousin once removed is either your first cousin’s child or your parent’s first cousin—same “first cousin” line, but one generation apart.
