His son Thomas Owsley was a Gateway Ancestor through the Poyntz side, the Owsley family prob. not a wealthy family. (Burke's says Thomas d. in Jamaica but he's buried very close to my house! Small world...)
The profile has this uncited statement I would like some help researching: "John Owsley was the son and heir of John Owsley of Trull, Somerset, and his wife Edith (Edwards) Owsley, daughter of William Edwards, of Winsham, Somerset. "
His Alumni Oxonienses profile says he had different parents: ""Ousley, John (Owsle) s. William, of Claypoole, co. Lincoln, pleb. Magdalen Hall, matric. 20 Oct., 1626, aged 18, " Note, they didn't really have a standardized spelling at this point, which is prob. why there are some errors in the ancestry. Pleb = commoner.
As the spouse of Dorothea Poyntz he's in Royal Ancestry v.4 pp. 294-5 which is not online. He's also in Plantagenet Ancestry, p. 656. which is not visible to me. If someone could check and cite his parents w/ a note that would be appreciated. I also re-started the merge w/ -103.
His da. Edith m. her 1st cousin Rev William Owsley & they had a son Rev John, both rectors of Glooston. So Rev. William Owsley's father, who according to the Alumni Oxon. was named Jeffrey, and this Rev. John were brothers.
I doubt he was an heir of much of anything in Trull, Somerset or Claypool, co. Lincoln since Edith's descendants only had property in Leicestershire, and it was enough for Esq status, Burke's is unclear how they acquired their wealth, I assume through marriage.
