The Peerys of Indiana and Illinois are predominately descendants of Joseph Peery I, the youngest of the five Peery brothers who settled in Augusta County Virginia in the early 1700's.
Josephs' wife is unknown but was reported to be of German descent.
Josephs' only known offspring was a son named Phillip Peery born in the 1740s, 1748 I think.
Phillip married Elizabeth Dilling, also of German descent, from Pennsylvania.
They and Joseph apparently remained in Virginia, but their children and grandchildren migrated to Indiana, Illinois, Ohio, and Iowa.
There are still Peery descendants today in those areas.
Don Peery in Monroe, Iowa has a lot of info on them. I don't have his address and phone handy but he is listed in the white pages for Monroe, Iowa. He is very helpfull and enjoys exchanging research info with other Peerys.
