Hi
I've been looking at the chart from the strnet ref that I gave earlier
I see a Lillias Stewart listed who married David Staig, Provost of Dumfries. Her parents were Charles Stewart of Shambellie (1705-1775) and Anne/Lilias Hay, daughter of James Hay of Dumfries.
Charles Stewart's parents were William Stewart of Shambellie (1660-1735) and Marion Stewart (?-1751).
There is no mention of Marion(alts) and George M*ckenzie on the chart. Although it looks possible that Marion was a younger sister to Lilias and named Ann as Hay Mackenzie after her mother. This just possible/probable.
