My mothers' maiden name was Labouef, which is the way she spelled it. It is a strange thing that I cannot get to the bottom of either. There were 10 children in the family, 7 living. Half spelled La bouef, half Le Bouef, and my grandfather, who came with the name had it spelled LeBeef... He marked it then with an X like you said, he could not read or write. I am really at a wall because I can't get any info from my mother. She is 77 and can't tell me her grandparents names. All she says is that they came from Quebec.
