Thanks to a tip from Randy Seaver's (Genea-Musings blog) where he recommended the county formation maps on: http://www.familyhistory101.com/maps I was able to track two ancestor localities. One was the Graham family of Monongahela, Washington County, Pennsylvania during the years 1776, 1779 and 1781. In 1776 part of what was then Yohogania (Virginia) is now Washington County. The Grahams I am seeking were in Washington County (possibly near Cross Creek) in Monongahela, PA. DeWitt Clinton Graham, whose father and two sisters died of consumption, lived in Monongahela and California in Washington County, PA before the Civil War. I am in the process of scanning DeWitts NARA Pension file which is quite large. DeWitt's mother remarried a man named Samuel Lewis who was a ship's carpenter. DeWitt (aka Clinton Graham) or just Clint in the pension file filed for disability due to consumption he contracted while on guard on Cheat Mountain in Virgina during the civil war.
The second ancestor locality that I found was the Edward Ward (born about 1800) and supposedly migrated from Allegheny County, Maryland with new wife Margaret Miller. He migrated to an area of Wayne County, Ohio which later became integrated into Ashland County, Ohio in 1846.
Another resource I frequently use is "The Census Map Book", by William Dollarhide.
