Hi Sue, Thanks to you and the other contributors for all this info, you dazzle this poor amateur.
I got part of the tree from the Rhys Christian tree on My Heritage and have been trying to confirm these entries.
I will contact our local LDS centre to see what I can dig upon the references you gave.
Is there any certainty of Williams birth date,
from Erics census data 1841 he was born 1811
In 1851 data he was born 1807 ???
I have a William on IGI born 28 June 1807, Parents F William, M Catherine Kelly all of Muaghold, it may be that Edward is not the correct father of William
There is a William C1890 F John Corkill M Margaret Cannell a sibling of James
I have siblings , 8 to Margaret Cannell, Robert 1783, Andrew 1785, James 1793, Margt 1787, Wm 1790, Andrew 1785, Esther 1799,James1793 These are all in the john(Dick ) line
