what it the relation between me and my cousin's son?
What is my cousin's child to me and what is she to my son (first cousin once removed, second cousin)? I get a little confused when someone asks what my relation is to my cousin's child or what my father-in-law's first cousin's son is to my husband. Calling a cousin an uncle-cousin sounds a little strange.
Children of your FIRST COUSIN'S children, are your FIRST COUSINS, TWICE REMOVED. So, your FIRST COUSIN'S son is your FIRST COUSIN, ONCE REMOVED. And your FIRST COUSIN'S son's, son's daughter is..........your FIRST COUSIN, THREE TIMES, REMOVED. Thus, your SECOND COUSIN'S child is your SECOND COUSIN, ONCE REMOVED.
