I love a puzzle, and this is a good one. I'm having difficulty with the 1798 Joseph because: (1) William would have only been 16 making him very precocious, and (2) the 1798 Joseph bp 1798 in Lonan is a member of the Raa Kneale family and he died in 1817 age 19. I'm wondering if William is not from the Raa family, but maybe is the one bp 1774 from the Graue Kneale family (which is closer to my family). I know nothing about this William other than he is described as eldest son in mother Jane's will of 1798. If this William married Ann Fargher in 1806, he's be 32 which gives plenty of time to have been married before. What is missing is another baptism for a Joseph and a first marriage for William. Then again, this could be all wrong too.
