Jack, I am researching a Wm.F. Carrigan, but that is a shot in the dark if you do not know where to start on yours, Wm. F. was in Early County, Ga. in 1830-1840-1850-1860. Mike Carrigan of Colorado said his family or part of it wound up in Roswell, New Mexico.......Start in your local library in the census for whatever state you live in.....Joan Herndon down in Georgia USA..........
