Find a Cousin

Tell us about one grandparent (or great-grandparent) who has died, and we'll work out who you're related to and how sure we are. Roughly when and where they were born helps a lot: “Mary Alden, born about 1928 in Plymouth”.

Invited to a family's site? Use the link in your invitation — every family site has its own address, like yourfamily.probablycousins.com.

What a result looks like

Every answer comes as one of five words — a colour, a shape, and the plain word for it — with how you two connect and which link in the chain is the shakiest, because a shaky link is still worth knowing about. See all five.
