MARC M COHEN
Actually, it's not so strange or rare, and certainly NOT impossible. My GGF Leizer Wolf Rosenberg in Tirgu Frumos, Romania, had two wives in succession, both named Leah and two sons named Izaak.
With Leah (1) Bercovici, he had Izaak, Avram, and Hanna. Leah 1 died in childbirth with Hannah. After observing Shloshim, 30 days later, Leizer married Leah (2) Schlaicher. They had two children, my GM Brahnia, and the second Izaak, although they pronounced it a little differently: Itzik or Aizic, according to different relatiives.
So, two Leahs, two Itzaaks.
