Early Origins of the Coulthropp family
The surname Coulthropp was first found in Norfolk where they held a family seat as Lords of the Manor of Calthorpe at the time of the taking of the Domesday Book survey in the year 1086 A.D. The survey showed that Calthorpe was a village containing a Church, 2.5 mills and 2 beehives.  It was held by Guerri and Osbert from Tihel the Breton from whom the Calthorpes are conjecturally descended.
By way of confirmation, another source notes: "he ancestors of Lord Catlthorpe assumed the name from Calthorpe, co. Norfolk, temp. Hen. III., and they are said to have been resident there from the time of the Conquest." 
The Hundredorum Rolls of 1273 had only one listing: Gilbert de Calthorp, who held lands in Norfolk at that time.

Coulthropp Spelling Variations
Since the Old and Middle English languages lacked definite spelling rules, Breton surnames have many spelling variations. Latin and French, which were the official court languages, were also influential on the spelling of surnames. The spelling of surnames was rarely consistent in medieval times, and scribes and church officials recorded names as they sounded rather than adhering to any specific spelling rules. Therefore, it was common to find the same individual referred to with different spellings of their surname in the ancient chronicles. Moreover, a large number of foreign names were brought into England after the Norman Conquest, which accelerated and accentuated the alterations to the spelling of various surnames. The name has been spelled Calthrop, Calthropp, Calthorp, Calthorpe, Cartharp, Carthrop, Carthropp, Carthorp and many more.
