I've been trying to do just that but I think he was probably born in Ireland as were his parents and siblings. At least that is what the 1841 census says that I'm feeling very strongly is his family...note the occupation of his father here is Fidewaiter

oops...just realized his Dad states he was born in Scotland. All the others are noted as born in Ireland. You definately should track down an original census image and have a look at that......
