Thank you for that correction on William Tateson. I will research his name now. I have also been in touch with other descendants of Trever (his name was spelled this way in original documents) and others.
I have many stories of this family, but one of the best is my Grandfather telling me that when he was eleven years old in 1900, his father Charles hired a lawyer in Iowa and sent him to England, with all of the original Trever Williams papers proving the Tennyson heritage, to claim a Tennyson estate thought to be unclaimed. The lawyer never returned from England, the lawyer's family disappeared 6 months later, and my G Grandfather never spoke of the issue again.
You having mentioned there being bigamy involved fits perfectly with my theory. John Tennison (b. 1784) of Preston by Hedon married Ann Foster in 1802 and then disappeared from history. John Tennison was related to Alfred Lord Tennyson through his GG Grandfather Michael Tennison (b. 1663 in Keyingham, Yorkshire). My Grandfather wrote that John (Tennyson) Williams was thought to have married a commoner and disowned by his family. It fits that John Williams was an educated man, being that he was the only one on the marriage certificate that could sign his name.
I would very much like access to Thomas' family tree (all I know of Thomas is his wife Mary and one son John who was married twice), and I would also prefer to communicate out of the public view, but don't know how this would be done. Please advise, and thank you for your response.
