p.	p.	Date	Motions
136- 137	359	1 Nov 1813	The last will and testament of John Armstrong deceased was this day exhibited in Court and proved by the oaths of Isaac Clark, [p. 137] and Francis Whiteside subscribing witnesses thereto and ordered to be recorded and on motion of James Whiteside the executor named in said will, who made oath thereto (he being released by the will from giving bond security) certificate is granted him for obtaining letters of administration on the estate of said decedent in due form.
137	359	1 Nov 1813	Ordered that Henry Clark, Isaac Clark, Simon French, Uriah Hatcher or any three of them being sworn before a magistrate do appraise the personal estate and slaves if any of John Armstrong deceased and report.

I presume John ARMSTRON is James's brother-in-law, though there hardly seems time for James's sister, Susannah, to have married twice by 1813 (John ARMSTRONG was supposedly her second husband, and she was only born in 1791).  James seems a little young (he's supposedly only 19) for such responsibility as being executor of a will, but I don't know who else this James could be.  I wonder if we have the birthdates correct for James and Susannah?  Isaac CLARK could be James's uncle or one of several cousins of that name.  Simon FRENCH is James's second cousin.  It doesn't say whether Henry CLARK is junior or senior — Henry CLARK, Sr., is James's grandfather; Henry CLARK, Jr., is James's uncle.   I don't know who Uriah HATCHER is.

DBI-358, Sept. 22, 1818, from JAMES WHITESIDE of Missouri Terr., St. Charles Co., to JOHN PETTUS, for $798.00, 100 A. on the West Fork of Red River, orig. patented to Elijah Fisher, & by him deeded to James Whiteside, from a beech on the State Line on the East side of the Creek, in metes and bounds. S/James Whiteside, Rec. 22 Sept. 1818

John Pettus FINLEY (mother's maiden name PETTUS) married Hester CLARK, James's aunt.  I don't know just where John PETTUS fits in.
