Hi, Your grandmother Leona was a twin daughter of William Calzy Halfacre who is the brother of my great grandfather, Milo LaVern Halfacre. So I guess that makes us cousins????William and Lavern were 2 of 10 children belonging to William Jefferson Halfacre and Roxie Ann Daggett. I believe William Jefferson Halfacre is the son of Jacob Halfacre who died about 1829.
My grandmother married Arthor Rosco Halfacre and their son is my father, William Charles Halfacre.
