I am currently completing a research project on an organization that was formed in Chicago in 1938 called the Ulster Irish Liberty League. The driving force behind the group was Bernard MacGillian, originally from Derry, and its main aim was to publicize anti-Catholic discrimination by the unionist regime and support the cause of a united Ireland.
The group remained active in Chicago until the early 1970s.
If any of your readers has information about this group, I'd be grateful to have it.
