The will of Mary Nash names her "sister Walker" as legatee (i.e. Jane Curle Walker, wife of George Walker III), and her "nephew George Walker" (i.e. George Walker, Jr.), as legatee and executor; thus identifying George Walker Jr. as the son of her sister and George Walker, Sr. Mary Nash was born Mary Curle, sister of Jane Curle, and daughter of Nicholas Curle.
will of Mary Nash
As noted above, Nicholas Curle named 4 children in his will of 1714: Pasco, Jane, Wilson, and "the child my wife now goes with." This fourth child was Mary Curle, born in 1714 after Nicholas's death.
She first married Alexander Hamilton [15]. This marriage is confirmed by Alexander Hamilton's will of September 17, 1746 [16].
Her second marriage was to John Nash of Prince Edward County [17]. The marriage was proved by the oaths of Mary's niece, Priscilla Curle, and her half-sister, Martha Sweny.
The will of Mary Nash [18] is dated October 22, 1765. After several specific bequests, Mary states:
"Lastly I give and bequest to my Nephew George Walker the residue of my Estate…"
This legatee is Col. George Walker III of Prince Edward and Jessamine, KY, son of Mary's sister Jane Curle (Jr.) and George Walker II. Two lines later Mary names him again, as executor of her will:
"I do constitute and appoint Mr. Cary Selden and my Nephew George Walker Executors of this my Last Will and Testament."
Mary also identifies her sister (Jane) as having last name Walker:
"Item I give to my sister Walker all my wearing apparel and all my Rings."
Mary also mentions legatee Jane Booker, her niece. Jane Booker is the sister and only sibling of Col. George Walker III, as mentioned in their father's 1773 will [19].
Finally, Mary Curle's will mentions several Curles as legatees (descendants of her deceased brother, Wilson Curle), including her nephew Nicholas Curle, and the child Mary Curle of another nephew, David Curle, who was deceased.
