Shirley May Webber

I am searching for information about Shirley M. Webber, born in 1941 in Belfast, Maine, I think.  She married a man by the last name of Ladd, and I have been unable to find any information on him.  They were married around 1960 and they had four children.  I searched the Maine genealogy network and the Ancestry.com records but had no luck.  Shirley May Webber is the daughter of Lloyd Leander Webber and Priscilla Ruth Stevens.  Can anyone help???
