Yeah, I agree we should consult a lawyer about it, but it’s 50 years after his death, which seems like a sufficient time that objections about reputation or damage to his estate wouldn’t hold water.
Edit: See other response—this should not be a problem.
Per my other comment, it seems there isn’t anyone to “confront us,” or at least, no one who obviously can authorize this, which makes objections seem unlikely and unreasonable.

FWIW, my guess would be that it is, or can be, legal, but that if they confronted you, you would want to change the name anyway.
