His father had inherited Shotwick Park, Cheshire, and other property through his second marriage with Catherine, daughter of Mr. Salusbury Lloyd, the M.P.
[1] Owen Brereton succeeded in 1756 to Shotwick and other estates in the counties of Chester, Denbigh, and Flint on his father's death[2] and also took Salusbury as (an additional) surname.
[2] In September 1742 Brereton was appointed Recorder of Liverpool, an office he retained till his death, a period of fifty-six years.
When he proposed to resign in 1796, he was requested by the corporation to retain the situation, and they appointed a deputy to relieve him of the pressure of its duties.
The paper on Brereton Church contains several unaccountable inaccuracies, which have been commented upon by George Ormerod in his History of Cheshire.
