I have Swale family near Fayette County on my tree. Isabella Swale was married to George Barker and they came to Iowa in 1857 and settled in Chickasaw county (adjoins Fayette). Her brother, James followed them over here after they settled and possibly another brother as well. In the 1860 census there is a William Swale,age 50-farmer that owned a lot of land. The other brother was possibly Thomas Swale, and his wife Elizabeth. On the 1860 census they have three kids. You can check out the 1860 census online. I also have information on the family from England.
