Alemar/Alemarus was given land by William the Conqueror for his services in helping defeat King Harold, the Anglo-Saxon in 1086. This land is in Tilton in Rutland, co. Leicester., England according to the famous Peerage and Baronetage books, c1915. He is listed as the illegitimate son of William the Conqueror is some 2nd hand sources, but this is highly in question. This Digby family went by the name of Tilton when their estate was in Leicestershire under the reign of King Henry II. Under King Henry III, they moved to Digby in Co. Lincolnshire, England instead.
Alemar's son in Jospeh Digby's book was Esquire William De Digby. In the genealogy produced in the 1500 or 1600 by the Digby family (currently housed in the genealogy collection at Castle Dublin) using their original land grants, wills etc. the oldest listed known Digby was Esquire De Digby De Tilton who was the father of Esquire William. His first name is unreadable, but is Everard according to the most extensive of early genealogies in Burke's "A Genealogical and Heraldic History of the Commoners of Great Britain, V. 4. It was hired to be researched by Kenelm Digby in the year 1634 for the cost of 1400 pounds in that day. Summaries of this early genealogy are given by Pennant in his tour from Chester to London sometime after the year 1634. The document on animal skin that I copied from a Mormon microfilm could easily be the same 1634 document that Burke is referring too. It is extremely faded and very difficult to decifer. Burkes' and the vellum manuscript basically agree except for Esquire William's wife's first name. (C-2162, 2163) Alemar is the father of the Esquire De Digby De Tilton listed at the top of the 1500's manuscript which would also account for a normal time chart of the births of the next several generations. He is also listed as Everard's father in Burke's book sourcing the 1634 history above.
