Mercy Dunn, daughter of Sarah (Fitzrandolph??) Dunn was born in New Jersey, ca 1770. Mercy married Peter Marlett ca 1786. Mercy is named in the will of Samuel Fitzrandolph (died 1788 in Sussex County, New Jersey) as Marcy Marlett, daughter of Sarah Dunn. >Is Sarah Dunn the sister of Samuel Fitzrandolph? >Who is the spouse of Sarah and the father of Mercy? Any thoughts regarding these questions would be most welcome. There were several Mercy Dunns but some, by age, can be eliminated as the spouse of Peter Marlett.
