The story that I heard about my last name was that my great-grandfather, whose first name I do not know, had 2 wives. His last name was originally Livers, and he had 13 or 14 children with his 1st wife. Then, I don't know if she died, or if they were divorced, but then he changed his name and remarried with the last name of Lyvers to differentiate between the two large families. If your last name is Lyvers, you were probably from the second wife and one of the 15 os so offspring of that marriage. I know this to be true of my family history, but it could be spelled differently according to your own family history.
