Interesting idea but probably unlikely, although the age matches.

Kate Hepburn has lived on the eastern shore of CT (Old Saybrook) for a very long time.
Oxford is a rural area, not too far from exclusive, rural-chic, celeb-infested Roxbury but it's certainly not known as a 'wealthy' area. If it turns out to be Hepburn we'll find out, eventually.
Of course I hope not and I hope that this elderly lady - whoever she is - survives.

The lady's name is Tilly Lundgren. She is mostly confined to home, they are mystified how she got anthrax.
