Not sure if this thread is too necroed but I'm also interested in Grace (recorded variously as Grizel and Grisel). Born Roy, in Knockando most probably, but we'll probably never know due to that fire.
Written account of her by her grandson is attached. [edit - too big to post, shared link:

Married first husband John Robertson 25/10/1783 of Forress and had three or four children by him (James, Alexander, Isobel, Thomas).
Frequent witnesses at baptisms are Alexander Roy, Isobel Roy and Alexander Christie - perhaps parents?
Husband dies and she has a second husband, reputedly her cousin, Alexander. I can't find a marriage record.
She has two sons by Alexander. (Alexander and James) (He's said to come from Boharm, but can't establish a birth record that looks likely).
She's buried in Drumblade churchyard, 24 Nov 1833, stone 290 with second husband Alexander. . Son Alexander is buried next door in 289 with most of his family, while son James emigrated to NZ.
