The lines that have been researched so far are the Buick, MacDonald, McLeod, Pyper and Blues families, who reached Arbroath in the late 1800s.
The earliest known Buick was a crofter and his descendants came south from the agricultural Mearns and coastal Johnshaven and Miltonhaven, St Cyrus, the old county of Kincardine. The Blues were mostly fisher folk from Johnshaven and Miltonhaven, and the Pypers from St Cyrus were quarriers and farm workers, the earliest known being a crofter. In Skye, the MacDonalds were a crofter and farm workers, and the earliest known McLeod was a stone mason.
The availability of work in the flax mills of Arbroath was a possible reason for the movement of all these families.
My grandmother Annie Pyper Buick was born in Arbroath and married David Cargill. They and their family found their way to Kilmarnock after a few years in Glasgow.
