I research a Jacob Peretzman, b. 1845 Latvia; d. 1933; he married Jeanette Shana Schmidt. They had about 10 children: Miriam, Hannah, Abraham (1878-1957) and Lena, b Feb 1888 in Riga, Latvia. There were 2 males and 4 females I do not have names for. Lena Peretman married David Diamond in New York -- Lena was my husband's grandmother. I have only a little info. but I have seen a photo taken in Tukum, so I know this family came from there. We might be able to collaborate.
