According to John's will,Susannah was his daughter. I find it odd that in John's will he mentions his children as: Susannah,Ann,Mary Greenwell and 4 sons: Francis,Robert,John and Joseph. And his grandson Jesse Floyd,son of Jesse.
And in Elenor's will she mentions her children as Jane Evens,Edward Greenwell,Philip Greenwell and 2 grand daughters Ann and Elenor Greenwell.
I have an Elizabeth Swales (1)married Floyd Jesse 5 Nov 1774 at St. Francis MD. The Eliabeth Swales (2)married Joseph Stone 5 Nov 1784
John Swales 1st married Margaret Goldsberry 1752/55 John Swales 2nd married Elenor Abell abt 1788.St.Mary's Co.MD. Elenor's parents were John and Jane Raley. The children that John mentioned in his will are probably his children byMargaret Goldsberry Swales/Swailes/Swails. Apparently John married Elenor shortly before his death. His will is dated the 16 Oct 1788 and he died 25 Nov 1788,St.Mary's Co. MD.
And the children that Elenor mentioned in her will were from a prior marriage. It seems that John's daughter Mary,married one of Elenor's son's!
