Best was a common name in England from the early 15th century, with an early branch in Worcester. There seem to have been a number of Best families in the 18th century with no evidence of links between them.
Bests appear Dorset parishes in the International Genealogical Index from XXXX. The 1851 Census of Dorset lists 268 people with the surname, distributed through 46 of Dorset's 274 parishes. Bests therefore represented about 0.15% of the 182,000 population. Of the 268 Bests, 30 (living in Durweston, Blandford, and Blandford St Mary) can be recognised as descended from William Best of Durweston. Other concentrations of Bests appear in the parishes of Wareham (45 names), Corfe Mullen (37), Lytchett Minster (26), Kimmeridge (15), Milton Abbas (11), and Poole (10).
There were many other Best groups in the South West of England, including ones in Surrey, Wiltshire, Somerset, Devon and Cornwall. It seems unlikely that most of these, and any Bests from other parts of Britain, are related to the Bests of Durweston
