Stan Goodman writes: "It does seem strange that Samuel took it upon
himself to anglicize the forename of a parent who was in Poland and
therefore not in need of anglicization, but we know little of Samuel
and his proclivities."
This odd practice was not uncommon in the States. In a number of
obituaries, I found family members who hadn't immigrated given
American names. In one case, Chana became Anna, and her husband
Raphael was written as Robert. Who knows why, though I can imagine a
number of possibilities.
