Several trees on Ancestry have Harry Woodman Boyd's father as Clarence Henry Woodbury, b. in Bellows Falls, VT, and his mother as Florence Rozella Boyd. It looks like Florence was m. to Charles Bradford Savage at the time of Harry's birth, and on the 1920 US Census Harry is entered as living with his grandparents (Florence's parents), also I haven't found any marriage record for Clarence Woodbury and Florence Boyd, so Harry might be from an extramarital affair.
