The monument actually says: to the memory of Elizabeth, wife of John Thorp, of Cudworth in Newdigate Esq who died aet. suae 29 (which I think I have worked out was that she was 29 when she died or at least that fits) AD 1624. On her monument there should be some Arms one in particular with Argent, three stags heads caboshed sable which should link her to her husband's grandmother ando this appears to be the only evidence that this girl was her grandmother - no marriage found to date!
The book that I am reading this from mentions the monument being in the chancel but it was written some 100 years ago so....
Hope that helps you to find it
