In his memoirs, John Finley Crowe, son of Benjamin Crow, names his grandmother as Mary Stuart from Scotland. While many researchers consider this recollection an aberration, his assertion should not be dismissed so lightly. It is significant that John Finley Crow never once mentions Ann Miller Crow in his memoirs, which is odd considering it's entirely possible he may have known her (she didn't die until 1811), and he certainly would have had ample opportunity to learn a good deal about her from his father as well as during the winter-long visit to his uncle William Crow in Kentucky circa 1819-1820. But again, he does not mention her. Rather, John Finley states quite plainly: "My grandfather raised a family of five sons: James, John, William, Benjamin and Jacob, and three daughters: Polly, Nancy and Rachel." Notice he does not say "my grandparents" - he clearly says "my grandfather."
My hypothesis is that John Finley Crow was correct, and that Mary Stuart died either shortly before or shortly after Walter Crow moved his family to Linville Creek, Augusta County, Virginia, where he met and married Ann Miller. She may even have been the mother of Walter's two youngest children born in Linville Creek, although that's pure speculation. That she survived Walter by some 20 years further suggests she may have been quite a bit younger than he.
