Would he be a weaver at 10?

Good point. But I think it is supposed to be “winder (ditto) pirns”, as written above.  He would have been that at age 10. What is written is “weaver ditto”, which doesn't make sense.
The whole census record / writing is just an incredible mess.
I think that what looks like 20 for George is actually 10 with a flourish to the top of the 1.

William was a busy fellow. I wonder what criminal activity he got up to?
Main street in 1862 record is the family address in 1851 census, and his mother’s address in 1861.
Orr street is where his brother John is living in 1871 census.
Brown street - John and George Williamson are there in 1865 valuations

[Neale1961]

The daughter Rachel Williamson born Carlisle, England in abt 1835 married James Preston in 1858.
1861 census has them living in Oswald Street.

[Neale1961]

Possible death for the father Adam Williamson in 1859, Bridgeton, age 66.

I think that what looks like 20 for George is actually 10 with a flourish to the top of the 1.

I also thought that might be the case.

There's a hint of just such a flourish in James' age above.

The 3 illegitimate children of Jane Peel and George Williamson born between 1856 and 1860 –
What street address is shown on their birth certificates?

I don't have their birth cert, William was 1 1/2 yr when he died in 1861 at 41 Ozwald st 
I have John Peel Williamson BC 1856 illegitimate mother Jane Peel, can't make out the address,
Between prison and everything else I think they are just all broken people and not a true family

[Forfarian]
