SCOBELL
As described in historical dictionaries
Patronymica Britannica (1860)
SCOBELL. Accorduig to Hals, this name, in the old Cornish language, signifies the broom-plant, and therefore takes its place, etymologically, with the illustrious Plantageuet. The family, whose original Tiahitat was the counties of Cornwall and Devon, have flourished, for a long series of generations, in kniglitly and gentle degree, in that jiart of England, and have written their name Scobbahull, Scobhull, Scobbel, Scobhill, Scoble, &c. The first of the name on record is Thomas de Scobbahull, .sheriff of Devonshire, in 1291. B.L.G. Scovell is not, as it might seem, a modification of this surname.
