My 5xg-grandfather, David Millar, was born at Dalricket Mill, New Cumnock on 24 April 1745. His parents were William Millar & Margaret Dick, who married in Dalmellington, Ayrshire in 1732.
I thought I'd throw that out there in case anyone searching for Millars of Dalricket Mill would like to contact me!
... I wonder if William Millar was a miller? :-)
