I have found John Smith and Priscilla on the 1871 and 1891 census records for Wales.

I am unable to find them on the 1881 census. I believe that Priscilla died in Cardiff in 1894. The family was then living on Cardiff. I think they were also fairground show people.

What I would like to establish is where Priscilla Roof was born. The only ones I can find other than those you have mentioned are in America.

There was a John Smith who was born in Coleford in 1834 whose father's name was Daniel. He was a carpenter and had Scottish connections. My John Smith reputedly had Scottish connections. However, I have no way of verifying this.

John Smith is probably the worst name to research.

Thanks for the information.
