'William Ingraham is shown to have been a son of Richard by the Proprietary Records of Rehoboth ...
In a deed of June 29, 1706, William Ingraham conveyed a tract of land in Rehoboth, in his own words, "to my Nefew obadiah Ingraham son to Jarratt Ingraham my Brother."
These records show definitely that William and Jarratt were brothers, and sons of Richard Ingraham.
There were some other Ingrahams in the locality who were in the proper age range to have been children of Richard, but whose relationship to him, however probable, can be only conjectural.'
This article also calls into question Savage's identification of Richard Ingraham of Rehoboth with the Richard Ingraham who lived in Northampton, Massachusetts from 1668 to 1683, whose will was probated in 1683. Richard of Northampton mentioned only his wife Joan and her heirs and "son-in-law" Calleb Pumry in his will.
