This study seeks to explore transnational communication among migrants of the Irish diaspora through an examination of the Orange Order's networks. It draws upon rare local and district records and press accounts to explain the migratory links and social worlds of Orange emigrants from Ulster. The substance of the study echoes the findings of Canadian historians who have much richer records than exist in the public domain in Britain. It demonstrates how Orangemen in Ireland came to recognise the diasporic dimension of their movement, and how members used the Order to negotiate some of the pathways of migration that were an important feature of their lives, and in the lives of the working class more generally. The essay generally seeks to demonstrate that the Orange Order acted as a network of friendship, camaraderie and support for emigrants and immigrants in the British World in the late nineteenth and early twentieth centuries.
