The Tree you allude to on Ancestry is indeed mine. I am satisfied with my side back to William Morris born abt 1781 in Waterford, John Livingston and Abigail Doughurty as they are well documented in Newfoundland , and their descendants documented in Quebec. On the Canadian/Scottish Austin side, I am comfortable with Dr William Austin who married Sidney S Morris. They too are well documented in Ceylon and Quebec. However from there back ie Robert and Ms Copland is speculative to date as these people have been "lifted" off Ancestry, mainly through Ancestry's"potential parent". I am not subscribed to either Ancestry or Scotlands People so verifying these will probably have to wait until I have more time in the Australian winter. However there do not seem to be any connections to James in Kent.
The reoccurrence of names in this family is a challenge; I have 3 generations of William Morris, and the son of the third William and Mary Ann Austin [ Robert William Trevor Morris] had nieces on his wife's side whose father was yet another William Morris !
