Nancy, Sorry I did not respond to you earlier. Prudence Lide's name and birthdate is in the Mixon books by John Leslie Mixson. He does not note where he got the information. He corresponded with many people besides doing his own research.
As to John's will. Prudence died before John and he had remarried. He named his minor children in a document with his second wife (and she named hers)which was made about the time of his death.
I said they might not have lived nearby because there were not any Lide names in the Church journal ofGloucestershire at that time period. They could have lived there, but their marriages and births were not recorded in the Church records. I have not found any civil records of marriages and births of that time period. The Lides that we know about lived a little farther up the river. I checked some Church journals when I was in that area, but not all. Donna
