Admiralty Court of York
Among the records of the Admiralty Court of York, held at the Borthwick Institute, is a collection of Constable's Returns of Seamen, under reference DRP/Adm CT.
It appears that the Admiralty, under the Lord High Admiral, required regular updates of potential mariners in case of war. The surveys were carried out via the Admiralty's Marshall for Yorkshire, and were addressed to the constables of the townships adjoining the navigable rivers of Yorkshire.
The requests for returns were printed and signed by one of the notaries working in the Admiralty Court in York.
Example of a Request for Returns for Bubwith parish
Returns survive mostly for the late 17th - early 18th centuries, and curiously some had a sum of money against the names, and a total of these monies, by parish, exists for 1707. The returns for Ellerton were disappointing and simply said 'nil' or 'none', but the names of the constables for Ellerton were given, as follows:
1707
Ellerton

William Lister - Constable
1733
Ellerton

Thomas Clark - Constable
1744
