Hi I tried to send you an email last Friday but I have no record that it was sent in my sent box so I can only assume you didn't get it. I have done a lot of work since I posted the message so had most of the details you supplied apart from exactly where Robert and Mary Rae settled I have managed to glean from scotlandspeople website. By the way Robert Rae's mother was Mary Graham.
Is your wife's great grandmother Mary Jane Wilson? I have only that she married in 1905. Do you have more recent details like who her children were and descendants from then until the present day? The scotlandpeople website only give births up to 1903 so I am a little stuck here in New Zealand!
Please email me at firstname.lastname@example.org and I can you supply a lot of information (60 pages) which you may not have, including the decendants of Robert Rae's two brothers John and Thomas. I have a number of children of Mary Graham and Robert Rae but haven't managed yet to find the families of their sisters.
PS My first name is Clare not Anne. I put both my names when I registered and the computer decided that Anne was my name.
