Can anyone help me with family history/tree information about descendants or ascendants of the following?

Josiah Allen Betts, born 1807 Sydney, New South Wales, Australia & Martha Marsden, born 6 May 1811, same location, died 1937. Josiah & Martha married in 1839 at St. John's, Parramatta, New South Wales.

Patrick Betts & Margaret, who had a daughter Louisa Elizabeth Betts, died 1987.

Thomas Betts & Mary Ann Watts, who married on 23 July, 1875 at Iron Bark Hill, Sherwood, Australia. They had a daughter Mary Jane 1853-1923

As I research my families widely, both for my own family tree purposes and as a gift to friends and their families, I would really appreciate any family tree and relevant research copies from anyone in any country who is researching the Betts name, or perhaps some leads to already existing websites where this type of information can be found.

If anyone wishes to send me information, either a Gedcom or a file attached to an email would be very welcome. I would be quite happy to send anyone who requests it all the information I have in return. I run Legacy 6 as a genealogy programme on my computer
.

Thanks for your assistance, everyone.
