I am a descendant of Robert FRATER of Wooler, Northumberland.
I don't have all details, but when Robert married Margaret ORMISTON the records gave his name as Robert RATTRAY and this has caused some difficulty in tracing details.He worked for the Duchess of Sutherland and travelled through the centre of Scotland to Balnakeil, where he died in 1854.Margaret died in 1849.
Their children were Jane (=David MURRAY 1/3/1840), Elizabeth, Margaret (= William MUNRO 4/4/1848), Mary (= John CAIRNS 25/5/1849), Agnes, Esther, Walter, Johanne, Jamesina.There may also have been a son Robert(?) who married Margaret WAUGH.We have been unable to find any birth for him, but he was in the same areas as the rest of the family.
If you have an email address, I can forward more details to you.
