- 1772 – mention of a “Hendricks” settling on some land near Waynesburg, Greene, PA (from Tenmile Country and Its Pioneer Families, pages 4 and 5). Waynesburg is about 50 miles south of Pittsburgh, and 27 miles due west of Redstone Township, Fayette, PA, where John eventually ends up (was “Menallen” township until a Redstone carved out of Menallen in 1797.). This is likely our John Hendrickson. The author speculates that it might be James Hendricks, but he’s in West Virginia at this time, not in the southwest of Pennsylvania. (Note: four people have taken mtDNA tests. This special test follows DNA paths from mother-to-daughter. Two of those mtDNA test end up in Greene County, PA, right around this time period. We’re using these tests to find the maiden name of Eve. I’ll let you know what we discover!)

A note about boundary changes. Just because you find a person on different records in different townships and counties, it doesn’t mean they moved around a lot. Sometimes they stayed in the same exact place — the boundaries moved around them! FamilySearch has a wiki article on each location and will tell you about all the boundary changes for that location.
