Harry Sorin was married to Sarah Udin. The Sorin family lived in Boone County, Missouri. Harry and Sarah Sorin are burried in the Beth Hamedrosh Hagodol Cemetery in St. Louis, Missouri, section 16B along with many of the Udin family. I am specifically interested in the name that Udin was derived from in Russia and where the family is from. Sadie Udin is my family tie thru my paternal grandfather. She was his first wife and she died in Ohio in 1912.I have found documents with the Udin name listed as Yudin and also Udian.
