Several years ago (about 10, I guess), my wife and I spent a couple of days researching the Keller name in the Public Records Office in Dublin. They had ALL the Ks in one book, by year or decade. We were able to trace Kellers in Ireland back to about the early 1700s. Kellehers also. But we couldn't find any before that. I suspect that Keller MAY have come over in the "Palatine" immigration, where the British were trying to populate Ireland with Protestants from Germany. Keller is a popular German name, as we all know. Some day I will have to go back and see what I can find. Perhaps we will take a sabbatical and go over for a few months, tracing our Irish, Scottish and English roots. Robert Monteith Keller
