John Dudney and wife Elizabeth of Montgomery County, NC

I have a Mary Dudney (b. 1790-1795, d. aft 1850) who married into my UPCHURCH line -- Allen Upchurch (b. abt 1779 VA, d. June 21, 1848, NC).

In the information on Mary Dudney Upchurch, there is note that her father, John Dudney (b. abt 1761, d. 1809) left a will leaving his estate to his wife, Elizabeth Kay (unknown) for her lifetime, and then it was to go to his daughters: Nancy, the wife of L.L. Page; Mary, the wife of Allen Upchurch; Elizabeth, the wife of Howell Upchurch; and Sarah, the wife of Wiley Ross.

What I'm trying to determine is just when Elizabeth Kay (?) Upchurch died so that I can try to find a copy of the assignment of the land to the daughters. I'd also like to get a copy of John Dudney's original will.

Anyone familiar with this line?
