Solomon Isenagle (1788-1848) was born in Frederick Co. MD, the son of Thomas Eisennagel, Revolutionary War veteran, and Susannah Spanseiler. Source: Records of Frederick, MD, Evangelical Reformed Church. Abraham (ca 1788-before 1860) likely descends from a different line than Thomas (yet to be proven). I have extensive data on both lines. I would be happy to share my substantial information on this family with anyone interested.
