:That would be good. At present we are not doing too badly, with, mainly, conveniently-available online recensions of scholarly publications, and also reference to the relevant bits of the website of the RCAHMW. The RCAHMW may be the very definition of a reliable source in this matter. I have just added another comment from the RCAHMW site, referring to the recently-published dendrochronology of the rafters etc. of Pen y Bryn. Since it's thus dated to after Elizabeth's reign I have also removed the "Elizabethan" comment.
