[3] Later working with his brother Benjamin, Clayton contributed to the Dublin Penny Journal in 1834 and 1835.
Also in 1835, he engraved a series of 13 "Views of Dublin and Kingstown Railway" after Andrew Nicholl.
Walter G. Strickland describes Clayton as "idle and a ne'er-do-well"[2] who appears to have been convicted of "forgery and uttering stamps" with his son, Thomas, in February 1834.
[3] Clayton and his son travelled to New South Wales as free settlers, as they cooperated with the authorities, but were not permitted to leave the colony.
[2] Clayton has a number of identified plates in the 1838 Picture of Sydney by James Maclehose.
