Trying to connect a Theophilus Smith Marshall from Perth to one in Greenock, both born within one year of each other (1803/1804). Parents of Perth TSM were Catherine Robertson & Robert Marshall & Greenock one's parents were Alexander Marshall & Catherine Crawford. Descendants of both ended up in Australia. I am trying to determine if fathers of both Theophiluses! were brothers of my great great grandfather, James Marshall, married to Helen Milne in Aberdeen @ 1799 Any information would be appreciated.
