There were likely several branches of DeLONGS in Ohio at an early date, but I will refer to one just on the off chance that they are related to your fellow. Jacob DeLONG born by 1755, resided at Pittstown, Albany Co NY (now Rensselaer Co), until 1800. (He was a Rev War veteran, a Rebel in the 14th Albany Co. Militia). In 1801 he and his extended family moved to Canada, settling in the Toronto area. About 1815 part of this family including Jacob moved to Geauga Co Ohio, where he promptly died in 1816. There were DeLONGS and PRENTICES there from that time,who were of his family, although part of the family remained in Canada.
