Thank you so much for looking. It was very kind of you, and I really appreciate it.
Good idea about contacting the Edinburgh council. I'll do that.
She's an interesting one, at least to me. Her husband started out as an ag lab and later was described as a gamekeeper (by her on his death certificate, though he was an ag lab on the 1841), and they lived somewhere outside Falkland in Fife. He died young in 1850 when she had a houseful of kids from infant to age 14.
One of the great mysteries of my family history, one I'd love to know the story of, is how she managed to get from there to having three of her sons in apprenticeships in Edinburgh. One became a cabinetmaker, another, my ancestor, a gunsmith, and the third a shoemaker who ultimately owned a boot factory and shop on Princes St employing over 40. He's the one buried closest to her, in another section of that same cemetery, with a not-inexpensive obelisk-style stone for a bunch of his family members. He's also the one who informed on her death certificate.
At the time of the 1891 census, she was a boarding house keeper, but by 1901 was described as the head of the household, an annuitant living with (or at least on the census with) a granddaughter.
