Mortlock Origin:


Origins of Mortlock:

This unusual surname is of Anglo-Saxon origin and is a habitational name from Mortlake in Surrey. It acquires from the Olde English pre 7th Century byname “Morta”, of uncertain etymology, but it may be from the fish-name “mort”, which means “young salmon”, originally given as a nickname, and the Olde English “lag”, which means wet pasture, or “lacu”, which means a stream. So, “stream frequented by young salmon.” The place name was first noted as “Mortelaga” and “Mortelage” in the Domesday Book of 1086, and as “Mortelak” in the Close Rolls of 1228. The surname advancement since 1273 contains the following as John Mortlake (London, 1565), and John Morelacke (London, 1581).

The language of the courts was French for the next three centuries, and the Norman atmosphere prevailed. But Saxon surnames remained, and the family name first mentioned in the year 1279 when Walter Mortelake held the estates.

The very first recorded spelling of the family was shown to be that of Walter Mortlake, dated about 1086, in the “Hundred Rolls of Cambridgeshire,” It was during the time of King Edward I, who was known to be the “The Hammer of the Scots,” dated 1272-1307.
