Hello Marian,
I am a Keyes decendant (my maternal grandmother was a Keyes before marrying).
She came from a large family (as did her forebears) and lived in Essex (Walthamstow, Epping etc) and my own parents lived in Chipping Ongar!
I have struggled to get far with the Keyes family, but I am sure there must be something somewhere to give me a start!
I look forward to hearing from you,
Catherine
