Hi, I think the John Winstanley listed as a watchmaker on the 1847 and 1848-49 census in Geelong, Victoria is probably the father of John Winstanley born Liverpool c1838. Have not been able to find the immigration record for the family, but likely to be under NSW immigration records given it is an early record. John Winstanley's mother is definitely Amelia on his death certificate, but like you I can find no record of her in Lancashire or Victoria. Is possible she died on ship during voyage, but not listed on Victoria's marine index. Further complication is that John Winstanley Jnr death certificate 1894 shows he had been in Victoria for 42 years, which would be 1852, but these dates are registered by the spouse or descendants and therefore not necessarily correct. I am researching the Winstanley family for the 150th anniversary of Cheltenham Pioneer Cemetery in Cheltenham, Victoria. The first born child of John Winstanley Jr and Mary Irvine, Amelia May Winstanley, was the 11th burial at the cemetery in 1865. Would appreciate any info anyone can give me to assist with this family.
