Recorded as Dearden, Deerden, Derden, Durdan, Durden and Duerden this is an English surname. It is locational from a place near Edenfield in the county of Lancashire called "Dearden". The place name and hence the later surname derives from the Old English pre 7th century word "deor" meaning deer, and "denu", a valley, thus, "the valley of the deer". Locational surnames were developed when former inhabitants of a place moved to another area, usually to seek work, and were best identified by the name development since 1579 (see below) includes the following: Elizabeth Dearden (1630, Chester), Edward Duerden (1631, Chester) and Robert Durden (1646, Chester). The surname is well documented in the county of Lancashire.

The first recorded spelling of the family name is shown to be that of Roberte Duerden (christening), which was dated January 11th 1579, in the Manchester Cathedral, Lancashire, during the reign of Queen Elizabeth 1, known as "Good Queen Bess", 1558 - 1603. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
