From what my mother said, my great grandfather came to the states and it was the person that took the info down that spelled his name the way it did, but one day we were talking to her cousin and she said it was because my g-grandfather was drunk when the babies were born and that's why. I don't believe the second version because my grandfather spelled his name Wejcman, my grandfather and one of his brothers and sister spelled it the same, another of his brothers spelled it Wecman and the last spelled it Weisman. To make matters worse, in the census I have also seen it spelled Wytzman.
