Daily AncestorZack
Zack is an old nickname for Zachariah or Zachary, found in American records of the 1700s and 1800s.
Zack is a short form of Zachariah and Zachary.
A gravestone or a family Bible may say Zack while a will or a deed says Zachariah. Search indexes under both forms so you do not miss him. Because Zack served for more than one name, see which full name the same man carries in other records.
