I have a Sarah Thumpston born 1844 who is the twin of James (he died 1883). Sarah married William John Wright 25 Jan 1861, Trinity Church, Wangaratta. Sarah died 1883 in Jamieson (registration district) and William John Wright died 29 Nov 1885. I have William and Sarah's marriage certificate and one of the witnesses was Joseph Timperley Thumpston, her father is noted as James Thumpston (Bushman) and mother Mary Ann Thumpston nee Smith. I have information on the Wright family if you are interested.......Sandra
