I am currently researching this end of my stepfather's family tree and have run into a bit of a road block.
I have the information for George Brough b.1831. The census for 1871-1901 have him listed being born in England. His death record has his parents listed as John and Eliza Brough. There is no information indicated where he actually came from in England. I haven't even found definitive proof that he came from the Yorkshire area and it seems like this is the same area most people researching the P.E.C. Brough line are stuck.
If any one has any additional information, please send me a message via email. It's my username at Hotmail dot com.
