My great-grandparents on my mother's side of the family were Nathan and Rita (Ritta) Goldenzweig who lived in Bucharest, Romania. I cannot find any reference to them on JewishGen or on MyHeritage.com / Ancestry.com. They had two children, a daughter Sylvia (1893-1972) and a son Sergiu (1896-?) who may have changed his name to Godeanu for political reasons.
Both Nathan and Rita would have been born when Romania was under the rule of the Ottoman Empire, but of course I don't know if they were born in Romania.
Any help in this matter would be greatly appreciated.
