Have found a census entry which adds up names and age and area-wise with my great granny. But, she's a servant stating that she's single. But it's her married name that's shown. She could, of course, have lied about marital status (I'm assuming she might not have been allowed to continue to work if married). Or it could be the wrong person and my g granny wasn't even married then anyway but...
Does anyone know more?
