If you have a fax, I can send you a worksheet page that my aunt used while tracing down our Harder person. Quite a few Catharine's. (Yes, spelled that way), so chances are yours is realteed. John, Michaelb, benjamin, Henry, Joseph, Hiram. William, George. All listed from census records. There was a William H Harder who died in 1863 from Diptheria, and then another Wiliam JR who married a Sophia Smith of Meredith. He then died at age 40 in 1875. Email me if you need this paperwork. Good luck.
