Dear Ms Leitch,
thank you for your enquiry. I have a lot of BMD and census information which I have verified on the official GROS site. I would be very happy to share this information with you. I conclude your Grandfather was Robert Ferguson born abt. 1855.
If you print out this message, you should be able to see my email address which is disguised by ancestry.co.uk to avoid spam. Please contact me directly and I will arrange to send you the information I have. There may be too much to e-mail to you.
I would be extremely interested in the family tree information you have as I have not been able to get past Alexander Izat and Jean Clark.
John Izat in Berwick is my first cousin once removed.
