I have a cousin married to a Lyons and a friend who is a Lynes.They are both from the same family but the named was changed within the family. As I have been told the grandfather of the friend name was changed by a school teacher who said they were spelling the name wrong. He was the younger brother of the cousin's father. That is all I know about the change of name. I am interested in the info you have on the family. I am willing to share info.
