Same here on the long search for Millers. I am looking for descendants of Paul Miller and Elizabeth Noel: particularly a Theresa "Wineard" who wasnamed as a niece of Theresa Clay in her 1889 will. Theresa Wineard was a resident of New Oxford, Adams County in 1889, but of course I can't find her...
If you use Google Books and search for Paul Miller and Conewago, or Paul Miller and Easton you will find quite a bit of information on the 1st Paul Miller in some old Catholic journals. He was one of the founding pioneers of Easton, PA as well.
