I am looking for further information on Dugald, who may have been a crofter. The birth record does not give John Paterson's mother's name, but the death record gives Christian McIntyre. I believe his father was Dugald Paterson, born 28 May 1770 in Aird. They married 15 Feb 1800 in Saddell And Skipness.
