This John Ripper meets the criteria established from wills. It is necessary to have John and Jenet to have a child having children so that they can have grandchildren which John (#2245) mentions in his will of 1616. In the wills there is a suggestion that Thomas, the son of John & Constance, had a cousin Daniel, although it is more likely to be a nephew Daniel, the son of Edward & Blanche. More information on the family home of Crawle (Crohall) can be found under entry of son Thomas in next generation.
Penny Demetriou-Miners and James Kitto have another child, a daughter Janet born about 1593. I have seen no evidence for this.
