I too have had trouble with a McKneale (McNeil) family. It came down to Esther McNeale having had two illegitimate children as follows. 1829 Catherine McNeale born to Thomas Callerton and Esther McNeale in Castletown. Then 1831 Isabella McNeale was born to William Jendon and Esther McNeale in Santan. In 1939 Esther married John Gawne in Malew. Catherine (our ancestor) took her fathers name. I don't know about Isabella. Could Richard be part of this set up?
