Heinrich KESSELBERG/CASSELBERRY d. 1729 isn't one of the original 13, but he got to Germantown right afterwards, and shortly after married a Catrin/Catharine ? d. 1768 by whom he had children Elizabeth, Derrick, Eve, William, John, Mary, Catharine, and Paul. Catharine was a member of the original Mennonite congregation. Could his wife be a daughter of one of the original families? Some of his children married into the DAVIS, BASSET, SHRACK, and ADDAMS families, and his grandson Jacob married Ann TYSON. I have more CASSELBERRY information. Gene in Gotha
