I saw that Eli Cohen and Allegra Pizante had, in most family trees online, two sons named Isaac. I found more solid data about the first one, Isaac Eli, born on 1914. It took a little more finding something about the Isaac born on 1924, but at last, I got it. He's the son of a Cohen father and a Pizante mother, as well, but Louis Cohen and Behora Rivka Pizante, in this case, and he was born in Los Angeles. Anyway, I'm sure most trees will keep having 2 Isaacs in them, anyway.
