I have located the 1920 New York City marriage record for a great aunt who was born in Ukraine (in or near Odessa), in about 1900. In the record she lists her mother's maiden name as 'Morrison', which I am certain is the Americanized form of the original Yiddish surname. My question is - what might the original name have been? I know that here in the US, 'Morris' was often chosen for a man whose Hebrew/Yiddish name was Moshe/Mausha/Movsha, so I am thinking the surname may have been a variant of 'son of Moshe', such as Moskowitz, Moiseev, and so on. What other options might there be for 'Morrison'?
