My ancestor was Scottish but moved to Wales and married in Wales. He has a fairly common Scottish name, William Knox, but it is rare in Wales at that time. I can find him on all the censuses in Wales, but it only ever says he comes from Scotland without any specific place named. And in Scotland there are lots of William Knoxes. I can also find from his marriage certificate that his father's name is William, and he is an agricultural labourer, which narrows it down a bit but unfortunately he was born before registration so the records could be patchy too.
So I had the idea of looking for any other people by the name of Knox in South Wales, as in my experience, often brothers or family members migrate together. I can find a George Knox, also with a father, William, in agriculture, who comes from Edinburgh or Edinburgh area. There a lot fewer George Knoxes than there are Williams so I am reasonably confident I can find George in the Scottish records and he does have a brother called William of the right age.
However I have nothing to link the two Knoxes together in Wales. They are both in South Wales, but not the same area. It could just be coincidence that they are both there at the same time and that they are not related at all.
Does anyone have any suggestions of anything else I can look for to either tie them together or find the date of birth of William in Wales or any other means of proving who he is?
Thank you if you got to the end of this!
