@Jacob Peres: His date of birth has been entered as 1865, perhaps as aconsequence of a recent profile merge. This can hardly be right: his father was born in September 1857, as multiply recorded in the All Lithuania database, and so would have been barely 7 years old when Jacob was born, and Jacob's mother would have been even younger. I think it's likely that the merge has been with the wrong person. This also casts doubt on the very precise date of death (May 10, 1958) that has also appeared on his profile. Unfortunately, no sources have been recorded.
