Greg is a masculine name that originated as a diminutive of Gregory, which comes from the Greek name Gregorios, meaning 'watchful' or 'alert.' While Gregory has been used since early Christian times, Greg gained popularity as a standalone name in the mid-20th century. It reached its peak usage in the United States during the 1950s and 1960s. Greg has a friendly, approachable quality with a classic yet casual feel. The name's brevity and straightforward pronunciation have contributed to its enduring appeal across English-speaking countries. Though less commonly given to newborns today than in previous decades, Greg maintains a steady presence and is recognized as both a complete name and a nickname.

Beag is a masculine name with Scottish and Irish Gaelic origins, pronounced similar to 'bayg' or 'byug.' The name literally means 'small' or 'little one' in Gaelic and was traditionally used as a nickname or diminutive for a younger son or a man of small stature. Historically, it might have been used as a term of endearment rather than a formal given name. As a given name, Beag remains extremely rare in contemporary usage, even within Celtic regions. Those who choose this name today likely have strong connections to Scottish or Irish heritage and appreciate its simplicity, distinct sound, and authentic cultural roots.
