Thanks Eric, you are a mine of information!
With the tangled Robert Gelling/Jane Kelly marriages, it helps a lot. My Eleanor Gelling was the daughter of one of these couples and I thought it was probably the Ballamillaghyn line, but on re-checking her Parish register marriage entry, both she and Thomas Clague appear to have signed (no x), so I will need to pull out my earlier information to ascertain why I thought she was not of the "teacher" line.
Again, thanks.
