William Caddick was reportedly well acquainted with Richard Wright and George Stubbs, both slightly his junior.
[1][2] From 1766 William, the artist, lived in Old Hall Street (his house was in the part known as North Walk), and he probably died there in 1794.
He married Eliza, or Elizabeth, Wood of Burslem, a member of the noted family of potters.
In 1780 W. Caddick, junior (North Walk, Liverpool), made the family's sole appearance at the 1780 Royal Academy exhibition, with a 'Portrait in the character of Circe'.
[8] One of these is a portrait, painted in 1747, of Aaron Wood, his brother-in-law, a worthy of whom it is recorded that ' he was never heard [or known] to swear, chew tobacco, take snuff, or whistle or sing in his life, and was considered the most lively, pleasant, and merriest man in the county' though Dibdin observes that "W. Caddick has not quite succeeded in telling us all this with his brush".
