Show ContentsSidnam History, Family Crest & Coats of Arms

The name Sidnam is of Anglo-Saxon origin and came from when a family lived in the parish of Sydenham found in the counties of Devon, Oxfordshire and Somerset. 1 2 These place-names were derived from the Old English terms sid meaning wide and hamm meaning water meadow. 3

Sidnam is a topographic surname, which was given to a person who resided near a physical feature such as a hill, stream, church, or type of tree. During the Middle Ages, as society became more complex, individuals needed a way to be distinguishable from others. Toponymic surnames were developed as a result of this need. Various features in the landscape or area were used to distinguish people from one another. In this case the original bearers of the surname Sidnam were named due to their close proximity to the wide water meadow.

Early Origins of the Sidnam family

The surname Sidnam was first found in Northumberland where Ascelin de Sidenham was listed in the Assize Rolls for 1202. Later, Walter de Sydenham was found in the Feet of Fines for Oxford in 1284 and John Sydenham in the Subsidy Rolls for Somerset in 1327. Later again, Richards Sydenham was recorded in the Assize Rolls for Lincolnshire in 1384. 4

Early Somerset records show John de Sydenham, 1 Edward; and Simon de Sidenham, 1 Edward III (during the first year of the reign of King Edward III.) 5

Sidnam Spelling Variations

Migration of the Sidnam family

For political, religious, and economic reasons, thousands of English families boarded ships for Ireland, the Canadas, the America colonies, and many of smaller tropical colonies in the hope of finding better lives abroad.

Early immigrants bearing the Sidnam surname or a spelling variation of the name include : Richard Sidenham, who arrived in Barbados in 1670; Mary Sydenham, who settled in Pennsylvania in 1682; William Sydenham, a servant sent to Virginia in 1674.
