Francis Moyle born 1815? UK. Died 1891 Australia

My name is Stephen Moyle and I live in Australia. I am a descendant of Francis Moyle and Eleanor (nee Oppy / Eddy). Francis arrived on the “Augusta Schneider” in Port Philip, Australia in 1852, his wife and children following 4 years later. I have done extensive research after they arrived in Australia, but am finding it very difficult in tracking down any information in the UK. All I have to go by is that Francis’s fathers name may have been William and his mothers name possibly Mary. I believe Francis and Eleanor were married in 1845? in Wendron, Cornwall. Francis was possibly born in 1815. Any information or assistance would be greatly appreciated. Also if I can be of any assistance with info in Australia, just drop me a line, or conversely anyone can supply any info. My email address is risste@bigpond.comRegardsSteve
