The records of individual ecclesiastical parishes include registers of baptisms, marriages and burials, as well as records of the churchwardens and Parochial Church Councils, parish charities, schools, clubs and societies.
Parish records were deposited at the Clwyd Record Office, following an agreement of 1976 between the Church in Wales and the Welsh County Councils.
The ecclesiastical parish of Southsea was formed on 7 May 1921 from part of the ancient parish of Wrexham, and parts of the parishes of Broughton and Brymbo. [Information taken from http://www.genuki.org.uk/big/wal/DEN/Southsea/index.html (last accessed July 2015)]
