Sarah, I believe I am also a descendant of your Joshua, through his son Philip. Our Joshua was b. 15 June 1759 in Rumford, Merrimack, NH and married twice. Once to a Polly Brown and also to a Ann Manning. Interesting you show Hooksett, NH. Our original research showed our Philip came from Hooksett with his family in 1818 to Rochester, NY and died 2 years later. His widow returned to NH and remarried. She left behind a son Luman, and our family has lived in NY ever since. Please let me know if you see any connection or whatever info you may have.
