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

Rebecca Sunderland born 1802 Yorkshire England died 8 August 1882 Kurrajong, New South Wales, Australia & buried August 1882 in the Churchyard, St. Peters, Richmond, New South Wales & James Ball. James & Rebecca married on 14 May 1849 at St. Peters, Richmond.

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 Sunderland 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.
