His 1st marriage was to Mary Copper (who was baptised at Northiam, SSX on 12 July 1778, the daughter of William COPPER and Frances NOAKS).
William Vidler arrived in the Colony of New South Wales aboard the Maitland on 6 November 1838 with his 2nd wife. Also on board were his sons & daughter William, John, James, Edwin & Sarah and their families. His son Stephen and his family came out to the Colony on board the Fairlie in 1841 and his daughter Kezia and her family arrived on the Edward Paget in 1842. His eldest daughter Mary Mummery nee Vidler arrived with her family in New Zealand in 1841 aboard the Lady Nugent, and in the Colony of New South Wales in 1843 aboard the Ann.
When William arrived in Sydney in 1838, he gave his age as 60, stated he was a native of Battle, Sussex, and that his parents were William and Mary Vidler. Unfortunately, there is nothing recorded in the Battle parish register that matches with this claim, and his precise origins are still unknown. However, it is possible that his was one of two baptisms shown in the Battle register:
November 23rd, 1773 - William, son of Richard and Mary Vidler
September 21st, 1770 - William, illegitimate son of Mary Vidler
Richard (the father of the 1773 baptism) and Mary (the mother of the 1770 baptism) were siblings. Their parents were John VADLER and Elizabeth BOWLING, who were married at Battle on June 3rd, 1742.
