Cousins - Queue
"removed" means "generation after you" example: your cousin's children (which would be 1 generation after you) would be your first cousins, once removed. your cousin's grandchildren would be your first cousins, twice removed. etc.
that's so cool your mom has double cousins! :D
some day i want to try to figure out who my 2nd and 3rd cousins are. 2nd cousins would be the children of the siblings of your grandparents. 3rd cousins would be the children of the siblings of your great-grandparents.
