Nothing is known for sure about this couple.If you immerse yourself in Endsley/Ensley research, you might begin to suspect a connection between this John and wife, Jane [we don't even know postively that her maiden surname was Kidd....] and the oldest John Endsley of Lincoln County, North Carolina who died before 3 June 1788 simply because you cannot think of any other likely prospects.
Researchers seem to know enough about descendants of other lines of Endsleys well enough that most would rule out other known lines as possibilities for being the family of John Endsley of Lincoln/Marshall County, Tenn.
We know that that John Endsley had sons, John and Alexander and are pretty certainArchibald Endsley was a third son.Because son, John's widow, Deborah, submitted the family register page of her family Bible with her request for a RW veteran's widow's pension, we know who all his children were and what became of them.
It's hard to find a whole lot of records about Alexander.He disappears from Lincoln County, NC records after the 1820 Census and shows up in the 1840 Monroe County, TN census.Two probable sons of Alexander were in Monroe County earlier.James is mentioned as early as 1823 in Monroe County Court records.Alexander, Jr. is in the 1830 and 1840 Censuses there.Of course Alexander, Jr. married Mary Ann Boyd and they migrated to Lawrence Co Arkansas.
I figure Alexander Endsley, Sr. probably died in Monroe County or nearby.After all, he was getting on in years.If he had to be age 21 to receive property from the settlement of his father's estate 3 June 1788, he would have been around age 73 [never mind what the census says. They weren't too accurate in that era] at the time of the 1840 Census.
Archibald Endsley probably turned 21 in Lincoln County, NC around the time probable brother John deeded him land formerly belonging to John Endsley, dec'd in 1797.Archibald is in the 1800 and 1810 Censuses of Lincoln Co., NC and was in a Lincoln Co militia regiment in the War of 1812.He appears in Lincoln Co. marriage records both as a bondsman and as a groom.The last I know of him is when he deeded land to John Endsley in 1815.
Right now one cannot rule out the possibility that the John Endsley with wife, Jane in Lincoln & Marshall Counties, TN was a descendant of John Endsley of Lincoln Co., NC who died before 3 June 1788 through either Alexander Endsley, Sr. or Archibald Endsley.
Please remember: This is strictly conjecture, not fact!
I advise doing your own original research on this line if you are interested in it.I have never seen another family line, regardless of surname, with as much erroneous information posted on the internet.
