What stands out about Jackson’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Prior to the establishment of Jackson, the townsite of Old St. John's was settled approximately 1.5 miles north of the current site of Jackson on June 2, 1856, by a Catholic colony of sixty Irish immigrants led by Father Trecy. The colony was one of the first towns settled in Dakota County, and the first Catholic parish in Nebraska. When the rising Missouri River began to threaten the town around 1860, all of the residents of Old St. John's moved south to what is now known as Jackson.
