That has to be Ann. Her burial spot is with her parents. The unmarried part of her makes we wonder why, as if caused by occupation or divorce or just what. Finding where she lived earlier is the problem. These people never stayed very long in one place, unlike my mother's side which we traced back to the mid-1500s. Until the digital age, her family disappeared after 1860.
As for Horsell in the 1880s and generation afterward, posh is an English term I have read describing it. I don't have any ancestors who ever lived in an area like it that then, so I summarized from these descriptions when Joseph and Mary Ann lived there.
Then it contained those beginnings with its stately homes. The town abounds with parks, cricket and squash clubs, and golf courses.
If this description of the 1880-90s is wrong, please correct me. I suspect strongly that Joseph worked for one of those stately homes based on his previous manor house experiences.
