Thanks for having me.
My Lehman lineage came during the 1st diaspora of Williams Penn's experiment. They immigrated during the first diaspora (Mennonites, Quakers, and Amish... aka Pennsylvania Duch) into William Penn's Pennsylvania.
My Gregg/Gragg lineage came around the second diaspora, as Scot's Irish from Northern Ireland. John Gregg, and his sons fought during the French and Indian wars, the American Revolution and the War of 1812.
Amazingly enough, both lines (Lehman's and Gregg's) worked their farms, not all that far apart in Cumberland County Pennsylvania. After that, my line of Lehman's worked their across Pennsylvania, thru Ohio to Iowa ( now the rust belt corridor), thru the mid-west to Wyoming, Idaho (where my Grandmother was born) then down to Fallon Nevada (where my grandmother met and married my grandfather, a recent immigrant from Germany).
My Gregg line sold their farms in Cumberland Pennsylvania and used the money from that and their land grants (from the wars) to pioneer and settle in the Shenandoah Valley (Rockingham and Augusta Counties) in Virginia. This is where my lineage verges with the Harrison's, Lincoln's and Boone's. The "Tunis Hood Book" ~ Dellmon O. Hood and the "Settlers by the Long Gray Trail" ~ John Huston Harrison really helped a LOT with source and reference materials (amongst other sources)
When Virginia split, part of my family was in Virginia, and part in West Virginia. Then my line moved from there to North Carolina. After North Carolina was split into other states, part of the family was in North Carolina, and part (my line) was in Tennesee. There is a Gragg North Carolina in Avery County, not Coffee's there :)
My line was in Greene County Tennesee. Also on the border of Tennesee and North Carolina. Across from Avery County.
