The English surname 'Thorogood' is derived from the old Scandanavian forename Thorgeat, meaning literally "Thor's Gate". In the middle ages it was believed that by giving a child this name they would be protected by the Scandanavian God, Thor.
The derivation is recorded as early as 1183 AD when a 'Hunfridus filius Turgoti' was featured in the Pipe Rolls of Staffordshire, whilst only twenty miles from where the family now resides, in 1273, noted in the Hundred Rolls of Bedfordshire may be found one 'Alicia Thurgod'.
Variants of this surname still in frequent use include Thoroughgood, Thorowgood, Thurgood and Thurgate.
The Motto associated with this name is 'Vincit omnia veritas' which translates as 'Truth conquers all'.
