This is interesting having just stumbled across this site. My father's name was Ian Marshall Dick, his father's name Allan Marshall Dick, my g-grandfather was called Allan Dick and my gg-grandfather was Thomas Dick. The ancestory is Scottish, possibly around Dundee / Edinburgh. I don't know if there is a connection but the double barrel name is rather a coincidence. Allan Marshall Dick's brother was called Archibald Marshall Dick. Allan Marshall Dick was a Lieutenant in the Royal Navy and latterly a river pilot on the Mersey at Liverpool, there may be other seafaring conections going back which may be of interest to you. Hope this doesn't lead you up a blind alley. Regards JD.
