Geneology Q -- would my father's cousin be my 1st cousin once removed or my

Question:The cousin number indicates the number of generations separating the person closest to a common ancestor from that common ancestor.

In your case, the common ancestor is your great grandfather. Both your father and his cousin are separated from your great grandfather by ONE generation (for your father, it is your grandfather -- for your father's cousin, it is your great Aunt or Uncle). Thus they are 1st cousins (1 generation separation from common ancestor).

The "removed" is the additional generations, if any, separating the second person (further away) from the common ancestor.

So with YOU, your father's cousin is still closest to the common ancestor, 1 generation separation, so you and your father's cousin are still 1st cousins.

BUT you are TWO generations separated from the common ancestor (your father and grandfather). So the difference (2-1=1) is the removed number. So you and your father's cousin are 1st cousins once removed.

BUT, your father's cousins CHILD would now be two generations removed from the common ancestor --- as you are two generations removed. So you and your father's cousin's child are 2nd cousins. And since you are both 2 generations separated, there is no "removed" as 2-2=0.

First cousin once removed. His son would be your second cousin.
