Hi Monica -- Thanks for these items: I had not been aware of of the link to info on James Stark, and much appreciate it.
Re. George Robertson Sr., here's a brief summary of what I have:
118. George Robertson
b.c. 1791, St. Andrew’s Parish, Edinburgh; d. 5 March 1853 age 62, at 28 Albany Street [why couldn’t he have waited till 1855 and the initiation of SR record-keeping?]; bu. Warriston cemetery, Edinburgh. William Robertson I’s will named George as his third and youngest son. George’s monument in Edinburgh’s Warrison cemetery reads as follows:“In memory of George Robertson, Esq., one of the Deputy Keepers of the Records of Scotland, who died 5th March 1853, aged 62 years And of his son George Brown Robertson Deputy Keeper of the Records of Scotland, who died 26th November 1873, aged 54 years, and of his Daughter Sarah Isabella Robertson, who died 18th March 1874, aged 40 years; also of his widow Eliza Brown who died 17th March 1877, aged 80 years, and of his eldest son William Robertson, M.D., F.R.S.E., who died 25th August 1882 aged 64 years. And of his daughter Eliza Robertson who died 3rd October 1901 aged 74 years. [Base] Also of Christina Rose, widow of George Brown Robertson, who died 14th September 1912 aged 68 years Also of William Rose, younger son of George Brown and Christina Rose Robertson and husband of Eleanor Mary Robertson, who died 24th June 1937 aged 64 years.” George was commissioned Joint Deputy Keeper of the Records of Scotland in 1809, and re-appointed under the Clerk Register on 31 Dec. 1829. He became (sole?) deputy keeper of records in 1835.
The one small discrepancy between my records and yours is that I have Eliza (Brown) Robertson's parents as George Brown and Margaret Clerk, and (down a generation), George B. Robertson's wife as Christina Rose.
I had not checked out ScotlandsPlaces yet, but certainly will do so now; thank you for that tip!
