You have raised a number of valid points, but this is my morning browse and I am late for work.
I will try and place on record my sources and will set up some sketch maps. Someone may like to give me a quick course on how to upload pictures as I don't know how to do this.
It seems that many familes in the area "are reputed" to have come with the FiztAllan's. The sources all qualify it thus as I don't think anyoe has any definite "proof".
"Fitz" was the Norman way of saying "son of" the Scots was "Mac" or "Mc" Irish "O" for grandson of. In the Welsh border country they adopted the Welsh style of "ap" or "up" giving ap Robert - shortened as a surname to Probert and Progers. In the Isle of Man they dropped he "M" from "Mc" giving "Cowan" instead of "McOwen". Therefore some surnames beginning with "C" are really "son of" names. I don't think this happened with Caldwell but I have referred to the English inspired renaming of the McAughwell's.
Not doing to bad when I am in a rush.

By the way - I still think the generic use of "Calwell" is of Irish origin and not Scots. In Scotland it would only have been a miss-spelling or it could be that that family had immigrated to Scotland from Ireland. Arthur Calwell the well known Labor leader in Australia was a staunch Catholic with Irish ancestors. My mother met him for what that might be worth.
