Mac,I find your message very interesting.I have been researching my Randolph County, NC Alexander family, but have been at a dead end at my gg-grandfather for several years.
My gg grandfather Joseph Alexander was born in 1811, in an area near the Randolph and Guilford County line.He was twice married, first to Catherine by whom he had a son name Jonathan and two daughters.Catherine died about 1842 and he then married Anna Hamilton in 1845.The oral family history is our family came from the Rowan Cabarrus County area of NC.
The information I have from a book in the Carolina Room at the Mecklenburg County Library "Hezekiah Alexander and the Revolution in the Back County" states that William Black Billy Alexander was around 18 years old when he and some friends in the Rocky River area of Cabarrus County blew up a wagon train of gun powder on it's way to Alamance County on May 2, 1768.I put his date of birth around 1750. I have so very little information on his son Jonathan, but I believe he was born in the early 1780's.
I learned from your post that Jonathan went to Randolph.So if he was the father of my gg grandfather Joseph, that ties in with the oral history.
I would be very much interested in sharing information with you.My email address is firstname.lastname@example.org
