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

John Farquharson, who married an Isabel Robertson on 8th or 9th March, 1793 and had a son Donald, born 12 August, 1796 in Scotland.

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 FARQUHARSON name.

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. .
