My Grandfather was Max Srulowitz (abt 1893) and his older brother (possibly adopted) was Isidore (abt 1884). The older brother was left with Max's parents and no one has any details as to him being a relative or a child of close friends. The parents never returned. I have found Isidore's family in New York and they grew up with the same mystery. Both owned Quilting stores. Both died young. None of us have names for the Great Grandparents, but we don't believe they ever came to America.
Isidore married Gittel (Gussie) Silverman who was also from Iasi.
Thank you for writing and I deeply appreciate any help with our search.
