Hi Raylen,
Welcome to Talking Scot!
Could this be Samuel in 1851?
Westfield Farm, Cumbernauld, Dumbartonshire
Mary Moffat, 60, Head, born Kirkintelloch, Dumbartonshire, Farmer of 120 acres emplying 4 labourers
Marrion Moffat, 22, daughter, born Cumbernauld, Dumbartonshire, Farmer Daur
Joseph Moffat, 20, son, born Cumbernauld, Dumbartonshire, Farmer son
Alexander Moffat, 17, son, born Cumbernauld, Dumbartonshire, Farmer son
Samuel Christie, 22, servant, born Nk, Stirlingshire
John Dow, 20, servant, born Glasgow, farmer servant
Peter Barrat, 25, servant, born Ireland, farmer labourer
Agnes McLean, 20, servant, born Mall, Argyleshire, house servant
Do you know what Samuel's profession was? Too bad he married before 1855 or the certificate would have given his parents' names
There is a family in Northumberland in 1841, father Robert, mariner, but mother Anne...

k
Children:
Hir??, 20, engineer
Samuel, 15, apprentice
John, 10 apprentice
Robt, 8
Only Robt and Ann were born in the county. The others were born outside the county... if it is Samuel, it should say born in Scotland though. Hmmm.
The only likely one I can see in Scotland is this (but if Isabella is the mother, it doesn't fit). Since the 1841 census doesn't give the relationship amongst the people, there is no way of knowing.
1841
West Hillton Cower, St Ninians, Stirlingshire
Isabella Christie, 55, born Stirlingshire, Farmer
Samuel Christie, 16, born Stirlingshire, Ag Lab
Alexander Christie, 8, born Stirlingshire, Ag Lab
George Cunning, 40, born Scotland, Ag Lab
George Clevenson, 15, born Stirlingshire, Ag Lab
Ann Canns, 15, born Stirlingshire, FS
Jean Cochran, 15, born Stirlingshire, FS
On the other hand.. could this be Robt and Mary in 1841 with some younger siblings of Samuel?
Lower Bridge Street, St Ninians, Stirlingshire
Robert Christie, 35, born Stirlingshire, Cabinet Maker
Marcy Christie, 35, born Stirlingshire, Cabinet Maker
John Christie, 3, born Stirlingshire
Robert Christie, 1, born Stirlingshire
Well, that's my contribution of the day... hope some of this helps

All the best,
Sarah
