For the record, the name change was done by the relative himself, not by "Ellis Island". The #ResistanceGenealogy lady is pretty adamant about that point. She found all of Abraham's paperwork, showing that he had started using the shortened name before he went back to the Old Country (where he returned from on this trip, bringing his family to join him). Other families' stories are very similar. It's complicated by the loss of outgoing ships' logs, which would have shown the names (1) sooner (2) without even the involvement of screening at arrival.

A minor point in such a ✊ letter, I know, but it's a myth that just won't die.

I haven't heard whether he responded to her or not.

with all that said... just when I thought Elon couldn't be more of a dick, he finds a way to lower the bar. What kind of schmuck rags people over generational trauma?!
