Horne/Drinkwater (General)
Not sure there's an answer... may be Susannah/John were also family names.

If Edward was not working on the land, and was going up and down the Severn! - he may have been married anywhere - and just disappeared. Checked the Church of Latter Day Saints, no record there at all.
Looking at a baptism record of a Thomas Drinkwater at Taynton - 17 July 1671 - he would have been approx 28 years old when he married Elizabeth HORNE widow in 1699.
By looking at A2A - National Archives, and the Gloucestershire Archives Online Catalogue & Wills, there appears (amongst other items) to be a record of a Thomas DRINKWATER, 1673, Taynton, re: land at Pauntley.
