Hello I am the great granddaughter of Moische Rowinski/ Rovinski who's name was changed in the United States to Morris Rowin. He was born in Kiev on October 30, 1898. He came to the United States on a holiday when he was 13-14 and stayed in the United States. He lived in Detroit. And was married to my great grandmother Sarah Baron. According to my grand aunt he came from a wealthy Jewish family in Kiev and had a brother named Samuel who might have been in the United States after or around 1930's but came after my Great grandfather was already here. He also had at least one sister who was a pediatrician in Kiev. I have found documents that his mother's name might be Matle and according to stories she was very well to do in Kiev. I am looking for any information that anyone might have about his siblings and parents and beyond.
Thank you for your time,
A searching granddaughter
