I do have information on this Call family, but most of it has come from LDS, and that's not always accurate. For What it's worth, I have two Philip Calls - one who died before 1763 and one who was born between 1760 and 1768 in Salisbury, NH. The latter one is a brother of Nathaniel Call and is the ancestor in my line. He maried Keziah Morrison at Sanbornton, NH.on January 22, 1795. Their three children were born in Magog, Stanstead, Quebec, Canada. Keziah's parents were David Morrison and Keziah Whittle. Keziah was born about 1773 in Amesbry, Essex, MA.
The first-mentioned Phillip above is the farthest back I have gone. He was the Father of Stephen Call, who married somebody whose last name was Danforth. Stephen and the unknown Danforth were the parents of your Nathaniel and my
Children of Phillip Call and Keziah Morrison are: Richard Call (my line), Whiting Call and Daniel Call. Richard married Philenia Turner in Magog on March 1, 1830. Their children were Alpha Willard Call (my great grandfather), Philemina R. Call, Albert G Call, Lionel S Call, James B. Call, Wolford N. Call, Olivia T. Call and Thaddeus C. S. Call. Alpha Willard Call married Ellen Martin and Clarissa Bell Call,(my grandmother) was one of their five children.
I have dates and details of my line. If you want to include my line in your genealogy, let me know and I'll post those dates.
