"Darby and Joan" is a term used to describe a happily married couple. In England, clubs for senior citizens are appropriately called Darby and Joan Clubs. The first mention of John Darby and his wife Joan is believed to be in a poem by Henry Woodfall in 1735. At that time Woodfall was apprentice to Darby, a printer from the town of Bartholemew Close.Photo credit: Paul Darby
