Hi,
I have some notes on Gordon's sister, Janet & his brother, George who was also a Plasterer in Ft William, briefly:
Janet Riach born 1838 Ballachulish & Corran of Ardgour, parents recorded as William Reach and Nelly McLennan. (IGI)
George Riach born about 1841, parents were William Riach and Helen McLellan and he married Ann McNiven, (born ca 1844) in 1865. Marriage Registered at Ballachulish & Corran of Ardgour. Her parents were Alexander McNiven (born ca1818 Innismore, Morven, Argyll, died 1890 West Larach) and Mary Livingston, born ca1822 B&CofA).
I have quite a bit more on George's family and a few certificates, send me a PM with your e-mail address if you would like them.
Regards,
