Nothing so far in my booklets but there are two mentions of the surname Ravenscroft in the Minigaff MIs. They might be worth following up -
* Jane Ravenscroft Taylor (d. Lanarkshire 1894, aged 58) m. a John Matthews (d. Newton Stewart 1873, aged 61)
* William Dunbar, land surveyor, Cree Bridge d 1818, aged 82 wife Margaret Scott, d. 1792, aged 40. 1st daughter, Ravenscroft, d. 1819, aged 44. A note on this one that mentions a Dr John Ravenscroft of Cairnsmoor - will 1783, Wigtown.
She might have been named for him or it could be a family name. I think it's worth checking.
