I am great granddaughter to Alexander Dill Gamble whose brother William settled in USA from Ramelton, County Donegal, Ireland having travelled there with his father William Reichel Gamble. Whether they travelled with other family members is not known by me. Robert and Anna listed as siblings but nothing known of their fate. William Reichel's wife I believe was Anna Scott not Errol. Son William married Phrenie Miller and his children William Miller and Anna Miller Dill Gamble had been born in Paris France. Alexander settled in the Warialda district of New South Wales and married Fanny O'Donnell, their 13th child Rachel was my maternal grandmother. Fanny died as a result of childbirth soon after.
My website on tribalpages under O'Donnell Dill Gamble holds much information.
