Name: Miss HAY , Heiress? of Lochorwart 1
Birth: ABT 1372 in Lochorwart Castle, Gorebridge, Midlothian, Scotland
daughter of Sir Thomas Hay of Lochorwart. [Burke's Peerage]
Note: Even though Miss Hay's brother William & nephew (William's son) David were connected with Lochorwart, somehow Miss Hay's son William Borthwick ended up with the land, because he built Borthwick Castle on the Lochorwart Castle site in 1430. Some histories say that James I of Scotland granted the land to William 1st Lord Borthwick, and he built Borthwick Castle upon the site of the older Lochorwart Castle. I would suspect that this marriage had something to do with the Borthwick family getting ahold of Lochorwart (also spelled Lockerworth).
