Yes, I hadn't thought about the fact that Joney would not have been adminx if she had been so frail all her life. I've exhausted my cache of wills too, but have most of the deeds here - will tackle transcriptions next.
I have assumed that the Charles who borrows from aunt Catherine was the son of Charles 1(b1687), the difficult son of John Mylrea & Elizabeth Shimmin BUT the ages don't compute as Charles 1 could not have had a son old enough to borrow from his aunt in 1729. So the lender, Catherine Mylrea, is the sister or sister-in-law of John Mylrea, father of Charles1? Any ideas?
