Hello Aghadowey,
You have been working hard I see.. The Killogue address is definitely the correct one for my connections . Don't know that Dervock has any connection.... Any ideas for John and James's father who I believe to be Adam McClure married to Mollie Tweed although the 1911 census states that John's mother lived with him then ( she would have been in 80's at that time) but he entered her name as Mary.This also means that his father was already dead before 1911. There has been a post of Adam McClure married to a Margaret Tweed,in 1853 which is an OK.date but can Mollie,Margaret and Mary all be variations of the same person?? I'm not sure..I will keep digging!!
