Any relationship to Obama’s Eric Holder?
First names often run in related families, with children getting first names that are also the first names of older relatives of their parents; their parents’ siblings, aunts and uncles, cousins, grandparents, ect.
Well, maybe that was quite normal in my parents’ generation anyway. I know it was also quite normal in generations before my parents; having done some ancestry research and seen that it occurred quite often for many generations back. Find a family name, find ancestors and you can often find first names repeating in the family line somewhere.
