I'm looking for more information on my great great grandmother Rebecca Jacoby, her parents, and other relatives. I know that she was married to my great great grandfather Isaac Kay, who immigrated to the U.S. in 1874, and they had 8 children togther. Isaac was born abt 1858 in Russia. Rebecca was born in 1870 in California. The only information I have on her parents is that they were born in Germany.
