Dear Douglas,

Also having a quick look on ancestry I found a 1841 Scotland census for:

Name: Elizabeth Wallace
Age: 12
Estimated birth year: abt 1829
Gender: Female
Where born: Lanarkshire, Scotland
Civil parish: Barony
County: Lanarkshire
Address: Main St No 99
Occupation: At Printfield
Parish Number: 622

and Hugh Smith 1841 Scotland census
Name: Hugh Smith
Age: 13
Estimated birth year: abt 1828
Gender: Male
Where born: Argyll, Scotland
Civil parish: Campbeltown
County: Argyll
Address: Salt-pans
Parish Number: 507

Also 1851 England census for a Hugh Smith born 1828 Scotland

Hugh Smith
Age: 23
Estimated birth year: abt 1828
Relation: Lodger
Gender: Male
Where born: Scotland
Civil parish: Birmingham
Ecclesiastical parish: St Philip
County/Island: Warwickshire
Country: England

I don't know if this fits as he is there with a Benjamin Smith 34 and they both have occupation as Tailors.

Hope I am not leading you up the proverbial garden path!

Kind Regards
Diane
