Hi Joan,
My ggggrandfather was Thomas McKneal, brother of Isaac - both sons of Thomas and Dorothy of Santan. I have heaps of information about Thomas's line now after hard but enjoyable work over many years. Under the will of Thomas and Dorothy, son Thomas inherited land in Lonan which was entailed. It passed down the line to my father's cousin, John McNeil in Australia in 1933. Sadly he sold it. (long before I was born). I would like to share the info I have and would very much like to know about your branch as well. I live in Australia where my ggrandfather John McNeil emigrated to in 1873.
