In addition to name variants, there were also pronunciation variants. My maternal GGF, Leizar Wolf ROSENBERG had a first and then second wife, both named Leah. By each wife, Leizer had a son named Itzaak (or Israel Itzaak). The family pronounced the name of the first one "Yitzaahk" and the second one "Itzik."
