Despite his early and strong connection to Freemasonry, it was not always clear that Dunckerley was going to devote himself exclusively to the Craft. We have already seen his enthusiasm for the Sober Society of Portsmouth, and he flirted with other clubs as well. The eighteenth century was famously a time for clubs, and Dunckerley may well have been a member of many societies about which we have no knowledge. Of those we have discovered, surely none is more evocative than his participation in the Honourable Society of Cymmrodorion, which he had joined by 1778, when he appears on its membership list. The Cymmrodorion was established in 1751 as a base for Welshmen in London. It was an initiatory society, firmly anchored in ritual, poetry and song. New members were proposed and balloted, and the initiation fee and annual subscriptions went to support the Welsh charity school and to underwrite publications in Welsh. The charity school was established by the Society of Ancient Britons, but the Cymmrodorion was founded in part to assist in supporting it. Annual subscriptions were instituted in 1777. Members of the Cymmrodorion had be Welsh or of recent Welsh descent, be able to speak Welsh, and to be willing to sing and versify during the meeting, at least under the influence of sufficient alcohol. The Cymmrodorion met monthly in taverns around London, and was a significant magnet for London Welsh.
