I think many of the Dyke families who came over in the 1840's and 1850's were from Prussia (Germany) and landed in Wisconsin, coming through New York first and then taking a ship down the Canadian route. A lot of those who came in the 1860's and on seemed to come from Sweden, Holland, England, and some from France. This is based on what I have seen in various census's I have viewed in my research. One Andrew J. Dike/Dyke who lived in Wisconsin, was born 1830's and his father was Isiah Dyke and mother was Rebecca Freeman. Isaiah? born probably 1800-ish. I don't know if my line is connected to them or not, just passing that along in case you may have a tie in. Dyke is a Dutch German name, coming from people who lived near the Dykes or levees.Immigrants who entered USA in 1850's were not necessarily poor, many were skilled, some were shoemakers, some were musically talented, but the ones who came much later on were escaping the potato famine and political unrest. Hope this helps some. Janice (Dike)Jones of Kentucky.
