Jean, when you are asking about the same family it is easier for people trying to help if you "Post Response" on a previous thread, so that someone doesn't try to look up the same records all over again:

Lois wrote a long and detailed message: "John Skillicorn, “son of John”, was baptized at Lonan, October 18, 1765, and died there, November 3, 1813, age 47. He married, at Lonan, June 14, 1794, Margaret Corrin. She was the daughter of Philip and Ann (Gelling) Corrin, baptized at Lonan, March 10, 1765, and died there, March 30, 1837, age 76. She is the sister of Catherine Corrin, who married Philip Skillicorn". (etc.)

Note "John Skillicorn, “son of John” not son of Henry.

I think you are confusing two families. Please look again at all the detailed information you have been given.

No-one knows more than Lois does about Skillicorn families in Lonan. Since she wrote the above message in 2005 she has transcribed all the Lonan deeds relating to Skillicorn, having already transcribed most wills, and has put numerous detailed trees on this BB.
Their marriage contracts are at: lawsonsiom.freevar.com/Marr_cont/_mcon-index.html

You need to prove your ancestry one generation at a time, not make a guess in the middle and state it as fact.
