Since my last post here I have made some progress in tracing the descedants Ralph Sillar's Mauchline. John and William continued to farm around Mauchline and Stair, while David became a Ships Agent and one of his daughters Agnes married Henry Dubs the famous Locomotive builder in Glasgow. Agnes married David Boyd a Librarian Stationer in Glasgow. Margret Married Duncan Grant in Glasgow. James Shaw Sillars married the Marion Miller daughter of George Millar merchant at Trongate Glasgow.
In good Scottish tradition the name goes on and so far I have found 6 Ralph Sillar and 4 Ralph Sillars descendants.
All I need now is for someone to take a photo or two of the Head Stones at Catrine and Mauchline - Any Ayrshire family out their?
