The name originated near the Surrey and West Sussex border, and was associated with a place-name, being a derivative of two Old English words: - strod = marshy place and wic = farm or dwelling, The Penguin Dictionary provides the meaning as 'dairy farm in marshy bushland'.
A place called 'strod wic' appeared in an Anglo-Saxon Charter granting some land near Steyning in AD 965. By 1330, references appear where the place has become associated with individuals, such as the Kirdford, Sussex reference to 'Boscus de Strodwike'. Reference also start to appear around this time (1340) to 'StrodewyKeswood in Kyrdeford' . This woodland still exists (in part) near the properties in Kirdford called Crouchland farm and Foxbridge, and is now known as Strudgwick Wood.
As a surname, very few early references exist, until the 15th century, when it becomes much more prevalent , with a Ric. Strodewyke, witness to a feoffment of a parcel of land, in Kirdford in 1437 . The name also becomes apparent in Chiddingfold and in Hambledon a tax collector called John Strodewick is mentioned in 1430.
The earliest person found with the clear surname is a John Stroudwyk, mentioned in the Sussex Feet of Fines dated 1362.
Early versions of the name of the form Strodewycke and Strodwyk use the 'o' reflecting its Old English origins of 'strod', however this spelling seems to disappear by the mid 16th century. Later versions include Strydwyke, Strudgwick, Stradwick, Stredwick, Stridwick,Strudweek, Strudwyck and Strudwycke, most of these spellings disappearing by the mid 17th century.
Many other variations occur, some appearing in only one generation, and probably the result of the 'preferred spelling' of the particular clerk who made the records, others being associated with many generations of a family
