Meaning & origin

Deloy is a rare American masculine name first recorded in 1916. It reached its peak usage in 1930, though it never entered the top 1000 rankings. Since then it has remained stable at minimal levels, with no births recorded in the latest year (2025). The name has no strong ties to any particular state or culture, and its etymology is unclear. It may be a variant of the French-derived surname Deloy (meaning 'of joy') or an invented name from the early 20th century. Despite its obscurity, Deloy has a distinct, straightforward sound that fits the style of other vintage names from the 1930s era.

Deloy appears to be a modern American coinage, first recorded in 1916. It may have been formed by combining the popular prefix 'De-' with a syllable like '-loy', or as a variant of names such as Deloy (possibly from French 'de la joie' meaning 'of joy') or Delois. Its usage peaked in the 1930s but has remained stable at very low levels since.
