Hi Alison.....
I think I have found Laura, in Scotland in 1861.......
Registration Number 784.
Registration District Castleton
Civil Parish Castleton
County Roxburghshire
Address Wpe Tunnel Cottages
LAMA Quarrell
Age 19
Servant
Female
Born England
She is in the household of William and Jane RITSON.
An****** do's not allow you to view , the actual images of the Scottish census ' but I feel pretty certain, that LAMA is Laura mis-transcribed......
Best wishes
