I'm only a decade or so late in finding your message, but here it goes:
Anna Treat (1749-1832) Anna's father: Robert Treat (1725-1766) Robert's father: Samuel Treat (1680-1734) Samuel's father: Reverend Samuel Treat (1648-1716) Rev. Sam'l father: Governor Robert Treat (1622-1710)
Anna has a sister Elizabeth (Bessie), and a brother, Captain Samuel Treat who was killed in November 1777 at Fort Mifflin on the Delaware River during the defense of Philadelphia. Multiple witnesses noted that he fought with great valor, and his loss was lamented in writings by George Washington and Henry Knox. Anna's husband wrote a letter to General Knox in 1783 in an effort to help the family claim his estate.
