John married Mary Jane Jory on the 9th of April 1884 at her family home “Kings Meadow” in Launceston, Tasmania. They had eight children; Colin, who took over the firm after his fathers’ death in 1928; Alfred, Rupert, Florence; Rose, Eva and Arthur. After Colin’s death in 1956 the business continued. Campbell's Pottery remained in the family until it closed in 1959. The pipe and brick manufacturing business closed in 1976.
Pipe and brick manufacture was the largest part of the Campbell business, but John Campbell's own interest were the hand-thrown decorative items that they manufactured. Like McHugh’s, Campbell’s employed workers with experience in potteries on the mainland, such as Bendigo, Bennett’s and Cornwells. Master craftsman like Denny Beckett were associated with both McHugh’s and Campbell’s. There is also some evidence of John Campbell having regularly obtained specimens of the high-quality wares being produced at Bendigo Pottery in the mid-1880s from a contact employed there, in order to make moulds from them.
This is what the real ones look like, so if you have any, I would like to take them off your hands for a reasonable price.
