Looking for John STEWART's brother Alexander before 1861, I wondered about the following.
1851
Glenalbert, Little Dunkeld
STEWART
Grace, Head, 70
Alexander, Son, 45, no occupation listed
William, Son, 35, Labourer
All born Little Dunkeld
1841
Glenalbert, Little Dunkeld
STEWART
William, 60, Labourer
Grace, 60
Alexander, 30, no occupation listed
David, 15, Shoemaker
