William Allen (1736–1792) was an English banker who was a co-founder of the first bank to be opened in Manchester and was also the father of a future bishop.
In 1760, he married the daughter of Tomas Clowes and, in 1765, bought Davyhulme Hall, near Urmston (now in Greater Manchester).
Byrom died in 1773 and Sedgwick in 1779, leaving Allen as the sole director.
[4][5] Two days later, the bank itself collapsed, Allen was declared bankrupt, and he had to sell his property.
[3] Allen and his family went to live with Robert Wainwright Ashley, an old friend, in their home at Park Place (now Castle Park House) in Frodsham, Cheshire, where he died four years later.
