There were several families using the name Zack in Uniontown, PA who were actually 'Zaccagnino'. These Zacks would be related to Zaccagninos in Scranton, Pa and Buffalo, New York. Santolo Zaccagnino (went by Zack), of Uniontown, Pa. is the brother of Guiseppe (Joseph) and Donato Zaccagnino of Dunmore (Scranton) Pa. I am directly from that line and have all that information. There are several other Zaccagnino families in Uniontown in the 1900s through 1930 and they are all related but are using Zack. Any information greatly appreciate and will share anything I have.
