I need help-advice and a look up.In gfathers obit it mentioned that he had a sister,Ida Weintraub Hertzberg, but I cannot find her.I just found out that it was wrong with the name of Aaron being one of his brothers so it could be wrong again with her being a sister.I thought that if the brothers settle in Chicago, that she would too-that looks not to be the case.I have material from othe genners that she and Joseph are from Latvia-that they had three children and that he was employed by a dairy. Both died in the eighties but when I sent away and receive her dc-no Weintraubs were seen as her parents.Thats the second question that I had for years-first being birth.If my gfaher was b in 1871-would his siser be born in 1891 and lived till the eighties? Can one see where they lived other then Chicago
