A church in Dufftown in Banffshire, Scotland with origins dating back to 525 AD, bears the Mortlach name.
He was born in Parkdale, Nova Scotia, the son of Sidney Freeman Spidell and Lucinda Ann Saunders, and was educated in Parkdale, in Mortlach, Saskatchewan and at the University of Saskatchewan.
Moreover, Gavin Dunbar, a 16th-century Archbishop of Glasgow, wrote in his Epistolare that Nechtan's see was moved from Mortlach to Aberdeen in the year 1125, partially contradicting the account of Boece.
The see is the successor of that founded in 1012 at Mortlach by Beyn, which was moved to Aberdeen, by Bishop Nechtan of Aberdeen in April 1132, during the reign of King David I of Scotland.
