I know the Irish people put up a memorial statue for the tribe trying to help, I’m a native guy from Oklahoma (Indian territory at that time, probably), it astounds me that a Native American tribe could know about something happening on the other side of the world, and it was a busy point in time over here in the 1840’s (the Mexican-American War about the same time as the famine, then the Civil War just a short time after that)
Contrary to popular belief, Natives were not "uncivilized". We spoke several languages, read, and followed same events that others followed across the nation. We had many kinds of news and word of mouth sources. Firstly, some of the same people that worked to oppress those in Ireland came over to America and were assigned to Indian lands and affairs. Secondly, some of the missionaries and nuns were also Irish or of Irish descent. Third, many Native Americans worked alongside Irish coming to America during the famine as immigrants in mines, construction, and many other jobs such as the expansion of the railroads. The Choctaw ultimately identified with the plight of the Irish and sent $170 having just survived disease and famine just 16 years earlier.
