for your interest. There are two John James Corkhills being discussed here. One was the descendant of William Mylrea & Elizabeth Clague (strong Lonan connections - Ballakilley) through their grand daughter, Jane - this is Colin Birrell's line. The other was on the maternal antecedant line for Jonathan Mylrea in South Africa. Can supply both family trees to anyone who would like to contact me at dibanks@ bigpond dot net dot au.
