The farthes back that I have information is an August Ey. He was married to Johanna Spritzke. Per the 1900 Census, both were born in Germany. I also found a source having them from Poznan, Wiekopolskie, Poland. Somewhere else I have Halberstadt, Germany. They departed Germany from Bremen on Ship Ocean. Immigration records have their birth in Prussa. One of their sons told his son that they were from Prussa. They arrived at Baltimore. I'm guessing that record keeping wasn't all that accurate back them. I can see a possibility that Poznan and Prussa were confused. My thinking is that Prussa is correct. August and Johanna setteled in Erie, PA. He was a machnist. Offsprings relocated to Rochester, NY. Does any of this fit with your information.
