Hello Averil,
Thanks for looking up your records.
You said your information came from Constance Radcliffe - Tree Bwoaillee Losht (2).
So this morning I had a huge search in my over-flowing study because I thought Philip could have sent me some CR Looney charts many years ago when he posted me others - and I found some.
I have solved one of the mysteries about your two John Looney 1745 birthdates despite no bapts that year - and I think it could be because of a typo!
C.R's Tree Bwoaillee Losht (2) has "John (1750-1804 E 2nd 1805 Bwoaill’trooan Dreemskerry (Spout House) m Margaret Hutchin d.1802 E 2nd 1803".
So she didn't have 1745, and it either will be a typo or you decided that 1750 was wrong and changed it to 1745. Then forgot it was you who had done so.
