Note: I'd like to extend special thanks to researcher Jared Nathan for sharing his work pertaining to 525395Denise, especially for providing a translation of her son-in-law's will.

525395Denise ___ is mentioned in the will of her son-in-law 262696Stephen Bettenham. (Specifically, the will mentions Helewys primam uxorem meam ["Helewys my first wife"], then Willelmi Bakere patris ipsius Helewys ["William Baker father of the same Helewys"], and lastly Dionisie quondam uxoris predicti Willelmi Bakere ["Denise the former wife of the aforesaid William Baker"].)1

As you can see, 262696Stephen's will also shows that 525395Denise married 525394William Baker.1

A land record shows that 525395Denise was still living on 13 October 1381, that 525394William had passed away by that time, and that 525395Denise presumably had remarried (since her surname is recorded as Hertle/Herthe). I haven't seen the original record, but two abstracts are below:2,3
