Very nice to hear from you and receive the information about Edward and his wife. I found Joseph Parker & two of his boys baptisms in the book "People of the Town of Bethlehem", pg.16, 1982-Bethlehem Historical Society. I'm only guessing that Joseph was the father of my John Parker because John, as well as the next 3 generations, lived in Bethlehem or Coeymans all their lives. John Parker married Sylvia Mosher 7/4/1815 at the First Dutch Reformed Church in Albany, NY. John was in the War of 1812 in Col. Jonathan Varian's regiment for roughly 3 months. He was awarded 160 acres for his service. John died in 1858, as Sylvia is made Administratrix of his estate. John & Sylvia are mentioned on the death certificate of their son, Robert Parker, my second great grandfather.
If you would like to share more about these families I would love to be in touch.
