Also, a word of warning. You can't just assume that CR's charts are always correct, even though they are usually very helpful. You need to double-check each generation going back from Daniel.

Robert's wife Mary's surname was not unknown as you have written. Robert Corkill married Mary Corkill in Maughold on 25 May 1714. She was buried in Maughold on 30 April 1744. That "E" on CR's chart refers to an Epis will left by her. (See BL's wills index.)

By the way, are there twins among Daniel's descendants? They were very common in the Ballajora Corkill families.
