My mother was Janet Daniels Dalziel, born in 1885 in Dumfrieshire Scotland.
According to my father (a highlander Bannatyne) the Dalziels couldn't possibly have a real tartan as they were lowlanders!
However I would be interested in any information you have on the name. There are a few of us in Australia who correctly pronounce the name "D'L" and we immediately assume they are "family." Otherwise it is "Dalzeel".
