Antonette Stern married an Aaron Weintraub in Galatz Romania.
In 1913 Aaron took 2 of his children to NY - Antonette took 4 others to London and France before being re-united with Aaron in 1921.
In 1913 Aaron went straight to his brother-in-law Meir Braunstein 40 Delancy St. NY. It appears that Meir's wife was an Etta/Netta/Yetta?, have found on the ellis island site that a Meir Braunstein and Hirsh Stern both from Galatz arrived together in 1900 in NY - no address.
If I can find descendants of the Braunstein/Stern families perhaps they can provide information as to siblings of Aaron Weintraub - I only know of one, my great-grandmother Esther who went to live in England in 1902.
Aarons descendants know nothing - they didn't even know about Esther until I found them in the US.
If anyone has knowledge of any of the above please contact me.
