Thank you for the reply. I think the Hoops came from PA, now that I am getting a better picture of this branch of my family.
It looks like my George Martin was born around 1784 (a 1850 census in Illinois has him at age 66) and was married to an Elizabeth Riddle back in Rockingham County. Possibly 3 out of his possible 5 children were born in and around there. His oldest might be Mary (b. 1805, Rockingham), then Aaron (b. 1815, Stokes), then William (b. 1816, Rockingham), next Richard (b. 1820, Rockingham). Two others were born on the trek West, Charity in Shelby Co, IN about 1826 and the last one is possibly a Wiley, born somewhere in Indiana. Mary and Wiley are assumed children based on an 1850 census of Edgar County, IL (attached).
If any of this seems to match I would greatly appreciate any information you can pass along. I know children were often named after grandparents (from both mother and father's side) so names repeat often... however, some names are just common, like "George." Until I had a hit on another descendant I was having the darnedest time searching "William Martin"! =)
