Thank you all so much for all your posts and information, everyone's information seems to be correct and matches to the Robert Crawford I am looking for. The 1851 census for the old age pension for Thomas, seems to be inline with what I have already found. I tried to google for the actual document, but was unable to locate it, I did find a transcribed version, but just list the names and ages of children, which is extremely helpful, although would love to see the actual document. I do know they had 5 children, Jane, Nancy (1844), William, Elizabeth (1854) and Margaret (1857), so this census record matches perfectly, and gives me more Dates of birth, and two more children of Thomas and Robert. I have found the families of Nancy, Margaret and Elizabeth, still on the hunt for Jane. You have all been so kind and helpful, I really do appreciate it. I am able to piece together more of my family.
I know I mentioned Adam Gibson, he was a carpenter also from the Bogstown Braid area, and would have been born before 1829.
