My GG Grandfather John Kennaugh was born abt 1833 Castletown, Isle of Man. Father named William, a farmer, and mother named Sarah Gillow is documented on John's marriage certificate of 1856. Marriage certificate also states John was an orphan. Date of arrival in Victoria, Australia unknown but obviously prior to August 1856 when he was married in Melbourne, Victoria to Elisabeth Sinclair of Scottish origin. Seeking any information.
