Have been doing some research on ancestors who consistently travelled back and forth from Ireland to the US. They would only stay in the US for a month and then go back again. Then to return to the US a few months later. And repeat the process.
What were they doing? Trading? Importing and exporting goods? Was this a common thing to travel back and forth?
Were they political or Catholic? There’s a chance that they were raising money for the IRA during the Irish war of independence. Trading certain goods (mostly liquor) for cash or even firearms. It was a common practice for the IRA to send people to American cities with large Irish populations like New York,Boston,Chicago and Philadelphia to ask for donations of any kind. They also repeated this in the 1960s during the troubles too. I’d have to know more about them to figure out why their trips were so frequent. Were they American Nationals or Irish Nationals?
