Hello oly
I am not sure if Hannah was a Teal or Waterhouse in 1901 as I have still to find info on when she was taken in by the Teals, and as there were no official adoption records then it will be difficult.
I have found a Martha Waterhouse of the right age in the 1891 census, but she is in the Bramley union workhouse and states she was born in Bolton Lancashire, so I don't think she is the right one as I know that Martha was born in Great Ouseburn.
I have written to North Yorkshire records to see if they can help.
Thanks for help so far,
Al.
