The name Zackery is an English variant of the Hebrew name Zechariah, which means "the Lord has remembered." It dates back to the Old Testament of the Bible, where Zechariah was a prophet who lived during the 6th century BC in Jerusalem.

The name Zechariah is derived from the Hebrew words "zachar" meaning "to remember" and "Yah" which is a shortened form of the name of God, Yahweh. It was a popular name among Jews during the biblical era and has been used in various forms across different cultures and languages.

One of the earliest recorded instances of the name Zackery can be found in the Domesday Book, a survey of England commissioned by William the Conqueror in 1086. In this record, the name appears as "Zacharias," which was a common spelling variation at the time.

Throughout history, several notable individuals have borne the name Zackery or its variations. One of the most famous was Zechariah, the Old Testament prophet whose book of prophecies is included in the Hebrew Bible. Another was Saint Zacharias, a 4th-century Bishop of Jerusalem who is venerated as a martyr in the Catholic and Orthodox churches.

In the medieval period, Zachary was a common name among European nobility. One notable bearer was Zachary of Angers (c. 1090-1153), a French abbot and chronicler who wrote an influential history of the Norman conquest of England.

During the Renaissance, the name gained popularity in Italy, where it was sometimes spelled as "Zaccaria." One of the most famous Italians with this name was Zaccaria da Volterra (1501-1588), a sculptor and architect who worked on St. Peter's Basilica in Rome.

In the 17th century, the English variant Zackery became more common. One notable bearer was Zackery Crofton (1625-1672), an Irish Anglican clergyman and author who wrote a popular book on the Book of Common Prayer.

The name continued to be used in various forms throughout the 18th and 19th centuries, with notable bearers including Zacchaeus Candler (1722-1790), an English Dissenting minister and author, and Zachary Taylor (1784-1850), the 12th President of the United States.
