Lois and al,
Sara Musia Zarkhin Sara Musia Zarkhin left testimonies in Yad Vashem after two cousins:
Leizer Fin Leizer Fin
and Icchak/Itsik Glaz Itsik Leizer Glaz
based on the testimonies she left after her siblings, we can determine her parents were Israel and Chawa Leja Gitel.
Based on the 1933 marriage record of Chaim Slonimski and Feige Shif, we can tell that Leja Gitel's maiden name was Glaz. (The index says Leja, but the Yiddish text in the original records says Leja Gitel).
This is how I concluded that Leizer Fin and Itsik Glaz are Sara Zarchin's cousins through her maternal grandparents.
Sara Zarchin's husband's biography says that the couple met in Tashkent and that Sara was born in Moskow.
Can't tell if she was really born in Moskow as it appears that he siblings were born in Užpaliai.
