The distribution of the JONES surname is shown in the figure below. It represents the occurrence of the JONES surname in the legal cases of England before 1700. The number of cases found recorded in the Public Record Office for 1) Index of Ancient Petitions (generally before Edward III (1327-1377), 2) Calendar of Close Rolls (AD 1381-1495), 3) List of Early Chancery Proceedings, Vol IV, for dates 1500-1515, 4) Lists of Early Chancery Proceedings Vol.V - Vol.X, 1515-1558, 5) Index of Chancery Proceedings (Series II) Vol. I 1558-1579 and for years 1579 - 1600 (given as Vol. XXIV), 6) Proceeding on the Court of Requests, Vol 4, James I (1603-1625), 7) Index of Chancery Proceedings (Series II), Vol. III, AD 1621-1660, and 8) Public Record Office, London: Chancery Proceedings, Bridge's Division, 1613-1714, Vol. IV, I-Q are included.
The counties colored blue represent those English counties which had less than three (3) cases during the period of study. They certainly cluster to the east and north of England. [Except for Cornwall to the southwest.] A more likely explanation is based on the following figure.
[Not sure why Cornwall shows a lack of those with a JONES surname. Anyone have any theories why? Please post any suggestions or ideas. ]
