It is indeed Frank, I see from your surname interests that you are of the Northumberland Proudman line, I have had contact with a few researchers on your side of the family in the past, so it is a pleasure to *meet* you.
I am trying to take the line further back but haven't had much luck in the past, the surname Wilson doesn't help! I saw this Will online and wondered if I could associate it with our Wilson's. In it Thomas Wilson leaves £200 to his nephew also Thomas Wilson, son of his late brother John, now - our Thomas Wilson would have been around the correct age (b.1767) to be his nephew but there is absolutely no evidence to support this except Wilson & Proudman set up the pottery some years later on the outer reaches of the Coleorton Estate. Now surely to my way of thinking he would have needed some capital to invest in this new venture, so it is tempting to form this theory. Hopefully if I keep digging some piece of the puzzle may turn up.
By the way, if you are interested in the history of the Pottery, Samuel T Stewart has produced an excellent book "Coleorton Pottery 1835-1938" which you still may be able to purchase.
By the way I am descended from Thomas Wilson's son William, then his son Thomas Evans Wilson, in case you were wondering.

Sue
