I'm guessing that she died in Newport, Shropshire. Here's why:
- the branch of the Alditheley/Audley family to which Agnes belongs resided in Staffordshire, which is immediately east of Shropshire
- Agnes' 1st husband [6000000003275349130] was styled "of Stokesay Castle" (in Shropshire)
- Agnes' 2nd husband [6000000007151874980] was styled "of Weston" (in Shropshire) and "of Newton" (now Craven Arms, also in Shropshire)
- Newport in Shropshire contains an avenue named Audley Avenue
*sigh* Let me try the profile tags again:
Agnes' 1st husband: Sir Laurence de Ludlow, of Stokesay
Agnes' 2nd husband: Sir Hugh de Weston, of Weston & of Newton
