Rev. William Robb (1763- 1830), my 3 x great uncle, was chaplain to Lord Elibank. It’s likely that this was Alexander, the 7th lord, born in 1747, who was an army officer and M.P. for Peebles, before succeeding to the title (on the death of his uncle, George Murray) in 1785. He was lord-lieutenant of the county and colonel of the local militia. He died in 1820. William Robb was an Episcopal minister at Pittenweem, Fife, from 1787 to 1789 and at St. Andrews from 1789 to 1820.
Interestingly (or perhaps purely coincidentally), Patrick Murray, who was created the 1st Lord Elibank in 1643, was the son of Gideon Murray (died 1621), who was minister of Auchterless in 1585, and later became an important servant of James VI.
I’ve yet to discover the connection between the Murrays of Elibank and the Murrays of Stormont. If our family records are true, and my 3 x great grandmother, Margaret Ricketts Monteith, was a grand-daughter of Viscount Stormont, then perhaps Rev. William had a role in forging the connection between the families?
