Mary Sisson was not a Sisson by either marriage or birth.She was b. Mary Lisson, as per the following:
Westmoreland Co. Deeds, Patents, etc. 20 July 1677, Mary Nicholas, widow, to my loving son Lewis Nicholas (here listed property).In case it shall please the Almighty to take to himselfe my sonne Lewis Nicholas . . .then all the aforesaid estate to my loveing sonne and his brother-in-law (meaning stepbrother) Nath: Pope alias Bridges (because he was the stepson of a man named Bridges), . . . If my sonnes should depart this life before the age aforesaid and myself be deceased alsoe, then the whole estate both of Nath: and Lewis to be equally divided between the surviving children of my brother and sister Mr. Danill Lisson and Jane Lisson.
There is a similar entry on the same date regarding her son Nathaniel's estate.This establishes her maiden name as Lisson.
Whether she had a previous husband is not known but not likely, but she was married to Nathaniel Pope, by whom she had a son Nathaniel.She then married someone named Bridges, and then Lewis Nicholas.There are many court records to support this, but this one contains three husbands names in one record:
8 June 1675 Mary Bridges of Westmoreland Co. unto my loving sonne Nathaniel Pope alias Bridges.(The term alias was used frequently in the colonial records, sometimes to identify a woman by both her maiden name and married name simultaneously, as when the first Nathaniel Pope transferred property to his then-married daughter as "Ann Pope alias Washington", or because a stepson was sometimes identified by his stepfather's name) . . . For natural affection.One mare . . . Below the entry is added on 25 August 1675. Acknowledged by Lewis Nicholas who married Mary Pope alias Bridges after his marriadge.
After Lewis Nicholas died she married David Wickliffe: "25 July 1677.Marry Nicholas, widdow, hath by three severall deeds of gife made over to her chilldren Nath: Pope alias Bridges and Lewis Nicholas severall goods and chattles. Mary hath invested me David Whitlife with the care and tuition of Nathaniell and Lewis and allsoe with there estate.I, David Whitlife, doe bind me that the children shall be brought up soe fare at schoole as to writt and reade.It shall be lawfull for Marry at her owne plasure to remove the children to the care of whome shee pleaseth. There is intention of marradge between Marry and myself. David (W) Whitlife Wit:John Washington, Danniell Lisson, Anthony Bridges. 20 Sept. 1677.Recorded."
So Mary, nee Lisson, then married Nathaniel Pope, ? Bridges (possibly a connection of Anthony Bridges, Lewis Nicholas, and last (I think) David Wickliffe II.
