In 1901, if it is the correct one - Christina PERCY can be found as Christina JOHNSTONE once again, b. c1879, Northumberland, aged 22. Which kinda fits with her baptism record "1 Oct 1876
Church of England, Tweedmouth, Northumberland, England", and single. She is a Parlourmaid at 6 Park Hill Rise, Croydon. Which naturally made me cautious because it is so far away from Tweedmouth....but... thinking about the facts that she was married and having a child so young, plus having the baby die, as well as her husband the following year, and not being able to find any Christina/Christian PERCY/JOHNSTSON records for that census period leads me to accept this one as correct.
What do you think?
