According to the family historians all my ancestors got kicked out of Europe and sent to North America pre-1780. English, Irish and German. The German branch arrived in 1654. The English contingent were on the Mayflower (2 great....Grandfathers) and the Irish came over between 1750 and 1780. Fortunately my grandmothers on both sides were serious genealogists who documented the lineages with original documents starting back in the 30's and 40's.
