There is a reasonable chance the the Jacob Hesser you are researching was Jacob Hesser, born Feb. 17, 1773 in Trappe, Montgomery County PA. Tradition indicates that his son John was born in 1795 and died in 1882.
His parents were Frederick Hesser, second generation of Palatine (German) immigrants and Catherine Doll (original Palatine immigrant). At that time, spelling was phonetic and varied. The surname Doll also was spelled as Dull.
