I have allthe names in my tree and both Simon and his wife's death records. Simon remarried to an Elizabeth after Mary died.
Simon died 09 Mar 1873, Stevenston, Ayrshire Scotland, Mary (Murphy)Brannan died 03 Jan 1856, also Stevenston. Which line do run from. I have spoken to many different lines from living in Scotland, Cananda and Austrilia. I am in the states.
You mention an O'Neil Family, do you have some names I can match to my tree.
