Sedley History, Family Crest & Coats of Arms

Early Origins of the Sedley family

The surname Sedley was first found in Kent where the family had three distinct branches: Sedley of Aylesford; Sedley of Great Chart; and Sedley of Southfleet. The oldest appears to be William Sedley of Southfleet who was High Sheriff of Kent in 1546. Aylesford dates back to the Britons when it was called Saissenaighobail, in commemoration of their having here defeated the Saxons; and by the latter, after their settlement in the country, Eaglesford, of which the present name is a corruption. [1]

In 1240, Ralph Frisburn, on his return from the Holy Land, founded a Carmelite monastery, under the patronage of Richard, Lord Grey, of Codnor: many parts of the building are entire, though the greater portion of the site is occupied by a mansion erected by Sir William Sedley, and now the residence of the Earl of Aylesford.

The Sedley Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Deo patria tibi
Motto Translation: For God, country, and yourself.
