Sorry Gadget I forgot I said I would stick to this thread.
Looks promising, I had seen the name Jean Lang in connection to Agnes but I think I was a wee bit stuck on looking for a Robert (2nd son as I thought).

Thomas was born in muirkirk. Jean I am Unsure, her marriage has her father as James, there seems to be three marriage entries in the names of Thomas Paton and Jean Templeton, Muirkirk 1808, Stonehouse 1808, and Lanark 1810
hope its not two different couples.
