My maiden name is Serr, and my Great-Great grandpa's name was Karl Serr. He was married to Elizabetha Sophie Knodel and they had 3 sons Karl, George and Andrew (Andreas). They came to the U.S. about 1900 from Worms, Odessa, South Russia. I have this Serr line back to 1548, however I can't find any information on Elizabetha Sophie Knodel. I would appriciate any help you might have!
