Anne,
link on four does not appear to be working.
Derbyshires were a Quaker family, and it might be worth asking at Manchester Mount Street Meeting House, or Frandley Preparative Meeting, near Stretton, (my last place of Quaker membership/attendance) what info they have, on the Derbyshires (some still attend on Sundays), or Cheshire CC archives at Chester, which might also be very useful.
regards,
Marcus
