The name Greg ranked 174th in popularity for males of all ages in a sample of the 1990 US Census.
This name is highly rated in the 1990 U.S. Census popularity survey of all ages, but after 1960 does not appear in the state data listing the most popular baby names.
Unlike classical Greek names, which often refer to pagan gods and goddesses, authorities believe Gregory's evolution was specifically Christian. It may have been derived from the scriptural admonition ''be vigilant'' (1st Peter, chapter 5, verse 8).
Use of the name has certainly been prominent in church history. Sixteen Roman Catholic popes, and numerous saints, have been named Gregory. It is also a popular traditional name among the Scots, who sometimes shorten it to Gregor.
