This ancient English surname of SIDES was a locational name meaning 'one who came from SYDE' a place in County Gloucestershire. The name was originally rendered in the Old English word SIDE, literally meaning the dweller by the slope. The earliest of the name on record appears to be SIDE (without surname) who was listed as a tenant in the Domesday Book of 1086. The name is also spelt SIDE and SYDES. Surnames can be divided into four categories; place names, occupation names, nicknames and patronymics. PLACE NAMES are the largest group and covers all those names first applied to people who lived in or nearby to a particular place. For example, Grove, Wood, Field, Meadow, and Street are obvious. Occasionally names were taken from obscure villages or hamlets which no longer exist and this can make research confusing. OCCUPATION NAMES cover nearly all trades which existed in the Middle Ages. These are numerous. It does not necessarily follow that such names as King, Duke, Earl and so on mean your ancestors were of noble blood. It is much more likely that such named people worked for the person referred to. NICKNAMES. This is a smaller group but in many ways more interesting. They usually originated as a by-name for someone by describing their appearance, personal disposition or character but which became handed down through the ages and did not apply to their descendants. For instance the name Black would denote a dark man, Little, someone small (or even somewhat ambiguously) someone tall. PATRONYMICS. This group covers all names which derive immediately from the owner's father. Many christian names which are also surnames have, over the years, lost the possessive form but the origin is still the same. Examples of this could be names such as Peter,Thomas, Henry - all names which became both christian and surnames over the years. Later instances of the name include Herbert de SIDE, who was recorded in 1221 in County Gloucestershire, and Michael ASIDE was documented in 1327, Adam del SYDE was recorded in 1332 in County Surrey.
