A number of family members over the generations, have been involved with the printing trade. Charles, the son of Charles Samuel Morris Kay, was born on March 24th 1805 and was listed in the 1841 census as a copperplate printer and after he and his family moved to Australia in 1842 he was employed by the Postmaster General's Department in NSW and printed the first postage stamps in Australia in 1850.

Samuel (another son of C.S.M. Kay), born March 6th 1808, and his son Charles (1849-1929) were both bookbinders by trade. Emma, an elder sister of Charles (born 1841), was a book folder.

Alan Kay, a grandson of William and Ann, was apprenticed to a 'general printer and newspaper proprietor' following the end of the second world war; other grandchildren who worked in the printing industry were Raymond Peach and Peter Kay who at one time joined forces and ran their own printing business; Leon Kay, who attended school in Fleet Street and then worked for Odhams Press; Leon's sister June was employed by a bookbinding firm in St John's Street, Clerkenwell, and whose daughter Susan, worked for the Daily Telegraph.
