1871 (Stockton) Durham look up

[njh]

Thanks to Geoff for finding my 1881 family 

This is one is not as straight forward I am looking for a 12 year old (around 12) in 1871 in Stockton.   She was born in Ireland and was called Helena Fitzgerald.   

Can anyone help?

There is a 14 year old Helen Fitzgerald listed as a boarder at a convent in Sheffield, also a Catherine aged 17 who might be her sister. If you think it's her, contact me on my own e-mail and I'll  scan the image to you.
