from Steve Watson of Austin TX 
I was taking a few moments to view your incredible website, and noticed that you might enjoy receiving the following record in regard to Samuel Perry that died in Chowan Co. in 1760. Apparently his wife in the year 1731 was a daughter of Thomas Docton, and I presume may have been the wife named "Susannah" named in Samuel Perry's will. However, I have not yet located a record other than his will abstract that identifies her by name. It is possible that Susannah may have been a later wife and not the daughter of Thomas Docton. The abstract of the record is as follows:

Oct 18, 1731. Perquimans Co., NC Deed Book C No. 41:  Thomas Docton, of Perq Esq, for "love I bear my son-in-law Samuel Perry" of same, planter---have given 180a on S.side of Indian branch, where he now dwells to a line between him & Benj Willson, at his death to gr-child Rachell Perry Oct 18, 1731.

Samuel Perry then sold this property on Oct. 16, 1756 and possibly the grandchild Rachel Perry (who was probably his daughter) may have died and left no issue, as
she was also not mentioned in his will 4 years later.

Oct 16, 1756, "Perquimans Co., NC Deed Book F." No. 209, Samuel Perry of Perq, Planter-for L30 pd by Samuel Bagley, of afsd-sold 180a on So Side of Indian Branch, adj Benjamin Wilson, formerly given by Thomas Docton, to Samuel Perry.  Test' Jesse Perry.
