Hello Kath
Thanks for your reply!
As I probably mentioned before, William (bn 1817) is my GG grandfather, but I haven't gone any further back at this stage. If you send me your address, I'll send you what I have so far (gedcom or pdf file??).
I have a fair bit of info re more current Exelby's in Qld. Are you doing any other parallel surnames that are involved with the Exelbys?
regards,
Chris
