Hi, I am researching Aaron Henry ZULLINGER, and his son, Robert L. ZULLINGER. I suspect the L was from Robert's mom's last name. Robert attended the University of Pennsylvania, and received high honors there. I am interested in him because of the one he married - Anna "Nancy" Reisky SAILER, the daughter of Randolph and Mary "Maud" Sharswood FAIRMAN. Aaron was born in Franklin County, but was raised, largely, in Philadelphia. Anyone having interest in these names, Let me hear from you! Vince
