I was thinking the same thing… isn’t first cousin one removed mean second cousin?
It makes my head hurt. I had a first cousin once removed who had this down pat; I struggle with it. The once removed refers to whether you are in the same generation as the person. Your first cousin’s child is your FCOR. The difference between first and second cousins is that the former share the same grandparents. The latter share the same great grandparents.
No, but genetically just as close. Second cousins at no remove, share the same great-grandparents. First cousins once removed mean that the parents of one was the cousin of the other. Franklin and Teddy were fifth cousins. Eleanor was Teddy's neice, meaning she was Franklin's fifth cousin once removed. We used to play bridge with a guy named John Alden, and he was a direct descendent of Longfellow's John Alden. His was wife was also an Alden, but a very distant cousin, whom he met at an Alden family affair. Naturally, one could not resist telling him to "speak for yourself, John."
Yes, it does for most of us. Some people are purists and insist on the once removed phrase.
