I am aware of the land grant from the Indians, which led him to remove from Exeter to North New Hampton. Are you also aware that he was married twice and had children carried off (or killed) by the Indians. I don't have a complete copy of the book here in VA, but will be going to Maine in 2-3 weeks and will get a copy then. I believe the book was written by a gentleman whose mother was a Dolloff. I believe his last name was Morse. It was published in the 1890's. In the foreword of that book is the various claims of his ethnic background. However, the name appears nowhere in Russian resources, but as I personally am aware, there are several families in the South Bavaria area of Germany, and all commercial name histories list the name as a derivative of Dollhof or Dolhof, which is a German "home" name. This would have some veracity with the recorded spelling of his name in Exeter in 1666. The land grant was much later. My gg grandfather stayed on at at N. New Hampton and cared for his parents in their declining days, then moved to Boothbay, ME, in 1845.
