They were fifth cousins once removed. Eleanor's father and Teddy were brothers, FWIW. For those keeping score that means that they shared 4th great grandparents (great-great-great-great-grandparents)/5th great grandparents so clearly very closely related. (I'm not sure for whom the grandparents were 5th great and for whom they were 4th great.)Weren't Eleanor and FDR cousins or some relation to each other?
EDIT: Nevermind, I found this. I imagine a lot of people might find they are this distantly related to their spouse and never knew it. That is six/seven generations...

I find it just a little bit weird that a family would have a son that lived for several months before dying in infancy and then reuse his name five years later on another son.
