Hi again,
Just noticed that you'd already mentioned the info about 1851 Census

.
Blame the heatwave and the fact I've one eye on the computer screen and one on Andy Murray at Wimbledon!!
It's possible Annie/Agnes died prior to 1851 Census as I didn't see anyone who appeared to be her when I looked. But it was also common at this time for women to revert to using their maiden when widowed so she could be else where under Grant, although would she leave her small children??
Good luck with your research,
Looby
