My paternal grandmother was a Crocker.
But her family were in Somerset (Bath, Shepton Montague, Crewkerne) back to 1759.
My paternal family of Garrad were in north Dorset, though!
Great Grandfather Abraham Garrad (1843-1897) was Station Master at Shillingstone (or Shilling Okeford as it used to be called) and my grandfather, Arthur James Garrad (1876-1940) was born at Shillingstone.
