A Henry de Tinstall bequeathed some land to a relative back in 1468. The relatives's name was Roger Heath.Roger was married to a lady called Alice( Nee?). Could Alice have been a duaghter or relative of Henry? This could explain why the land was given to Roger. Roger was also in the pottery business and lived near Burslem which is now part of Stoke- on-Trent. Do you have any other data of that vintage. I have some from the Heth ppoint of view is you would like to exchange.
