I'm also looking for CARSON families, born Ireland, moved to Scotland c.1859, Dalry, Ayrshire, then around Govan, ending up in the Dennyloanhead/Haggs area. Mine all seem to be miners.
Earliest I have is William CARSON and Ellen (Helen) McHUTCHESON (McCutcheon) who married in Newtownards, 1855. William, Henry, Maggie and Martha seem to have been common names. Ring any bells with you?
