Orontes,
You may wish to have a look at this website:http://www.edwardboyle.com/EB/Cambuslang/History/Cambuslang%20Industries%20C%20Findlay.pdf
Now go to page 29 where you will find a map of Cambuslang dating from 1859.
At 1807, your ancestors, George Stevenson and Mary Coochrane lived in Sauchiebog which is located at the top right of the photograph.
They had 5 children at 1807 but sadly they are not named.
Therefore John had at least 4 siblings and if he was born after this census,then that number rises to 5.
We also know that at least one of them was called Andrew Stevenson b 18 May 1802
Another, born after the census was William Stevenson b 28 May 1812
The obvious railway line and station didn't exist at this time as it was opened in 1849.
By 1841, their son John, wife Christina Ormiston and family were living in Cullochburn which you can also locate on the opposite side of the current railway line.
This is where John's father died in 1829 ( see Below)
1851 they were at Bushyhill which is quite clear on the map.
This area of Cambuslang is also where my own ancestors originate.
It sits at the neighbouring Rutherglen end of the Parish
I created this for you:

Note that there are 2 girls named Janet who died in 1847 and 1849.
We know that they were not the children of John Stevenson and Christina Ormiston
They seem to be children born to a John Stevenson and Margaret Lochhead.
There was another couple named John Stevenson and Mary Brown
Based on the names of the children, this John was the son of Allan Stevenson and Margaret Cochran.
I am fairly certain the George and Allan Stevenson were brothers and that their parents were possibly called John Stevenson and Margaret Gibb who married in 1766 ( banns read 12 Apr 1766)
Allan Stevenson and Margaret Cochran:Marriage Banns read 12 Mar 1790
3 children on 1807 census at East Cotes
