Sidnem is a name of ancient Anglo-Saxon origin and comes from a family once having 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

Sidnem 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 Sidnem were named due to their close proximity to the wide water meadow.
