Sue, I have a burial for Daniel Skillicorn 14 Mar 1739/40 Jurby and one for Joney Skillicorn 25 Jan 1799 Braddan age 84, which fits the 1715 baptism. Both from Brian's burial list.
Joney's 1799 will is transcribed and she gave everything to her nephew Pat. Brew smith, with "great affection". That's about all that I can add.
