About William De Turin, of Foveran
According to Debrett's Peerage, [ref. 11]
"The family of Turing, originally French, settled in the barony of Tourin, in Forfarshire, which they held for several generations.
Sir William TURYN attached himself to the fortunes of King David II., and shared that monarch's exile; his loyalty was however subsequently rewarded by a grant of the barony of Foveran, in Aberdeenshire, which his descendants held more than 300 years."
