Re: re: our Kevin's gran's aunt's cousin Sherryl
Gran: up two generations (mother of mother, or mother of father)
Aunt: up another generation then across to a sister
Cousin: shared grandparents, so up two then down two along a different branch of the family tree.
Total: Up five, down two.
So a common ancestor exists five generations up from the starting point, two up from the end point.
Take the lowest number: two, which implies cousin (three would be 2nd cousin, 4 = 3rd cousin, etc)
Take the generation difference: three.
Final result: Cousin three times removed, aka Sherryl.
