Erchenbald or Archembald[citation needed] was a mesne lord listed in the Domesday Book of 1086 as a tenant of nine manors in Devon and Cornwall, England.
[citation needed] The Domesday book records that Erchenbald held three manors in Cornwall and six in Devon, all as tenant of Robert, Count of Mortain,[1] who was a half-brother of William the Conqueror and held over one hundred west country manors as tenant-in-chief.
He came to England during the reign of William the Conqueror (1066-1087) and was a follower of that king's uterine half-brother Robert, Count of Mortain.
He went to Ireland with Henry II in 1171 and participated in Hugh de Lacy's plantation of the Kingdom of Mide.
[citation needed] The lands of Robert, Count of Mortain, became the core holdings of the feudal barony of Launceston,[5] in Cornwall, and the Fleming family continued to hold most of their manors from that barony, as can be seen from entries in the Book of Fees (c.1302) – for example, Baldwin le Flemeng is listed as holding lands in Crideho (Croyde) and also in Bratton' cum membris ("with its member (estates)"), both by then fees held from the feudal barony of Launceston.
