Hi Pam,
No, in 1851 census she is married with 2 children living in Liverpool.
Her name is so common it would probably be very difficult to find her on 1841 census. All i do know from 1851 census is she was born in Dumfries, no telling if she would have been there 1841 though.
Someone has kindly passed me some birth details from the Scotlands people website but there isn't a Sarah born in Dumfries on that!
I appreciate your reply and if you have any further suggestions of where to look, they will be greatly received. I have tried looking for her marriage to James,but as i have no idea where that would be it is quite difficult. I checked on Lancashire BMD but didn't find a match.
Thanks again
Amanda
