The Pyne family came  from Upton Pyne, near Exeter, c.1100:

Edith Elizabeth Pyne married Ayrton Chaplin, so the Pynes are related by marriage.
“The first Pyne of whom there is any mention was a ‘Herbert de Pine’ who, in the time of Henry I, held land at Upton Pyne, near Exeter. He proved a vigorous stock, handing down Upton Pyne for some 400 years in lineal male descendants and sending numerous shoots branching out from the district where Devon, Dorset and Somerset meet. His descendants still own the property of ‘Pynes’, which has been carried by a succession of heiresses into the Northcote family. The first of these heiresses was Constance Pyne, who married William Larder about the end of the fifteenth century; the last was Bridget Stafford, whose name reappears in that of the late Sir Stafford Northcote, who quarter the Pyne arms – Gules, a chevron argent between three pinecones, or – with those of the Northcotes.
The Pynes seem to have been for some centuries a prolific and successful family; they gave their name to the villages of Upton Pyne, Comb or Culm Pyne and Washford Pyne. The name occurs in various lists and rolls; Ralph Pine held the Manor of Ilrington by Knight’s fee in the time of Edward II, Thomas d’Pyne is mentioned in R. Glover’s Roll of Arms of the reign of Henry III, as bearing the same arms as those taken by Constance Pyne into the Northcote family.

In the 16th and 17th centuries, there were several families of Pyne settled in the West Country and so far differentiated from the original stock as to have slight modifications in their coats of arms, at any rate in their descriptions of them. The parent family at Upton Pyne retain the expression ‘pine-cones’, the term ‘pine-apples’ being substituted for it in several of the other branches. Among these branches was Andrew Pine of Stawell in Somerset, son of George Pine of East Down. George Pine was the ancestor of the Pine-Coffin family, settled for many generations at East Down in Comwall.

Captain Hercules Pyne successfully held the town of Lyme Regis for the Parliament during the Civil War”. (From ‘James, Pyne, Gregory.doc’)
