Meaning & origin

Deroy is a rare masculine name that first appeared in U.S. records in 1914, but it never reached the top 1000. Its peak year was 1935, when it saw its highest number of births. Since then, usage has remained stable at very low levels. The name is often considered a variant of Leroy, a French-derived name meaning 'the king.' Despite its low frequency, Deroy offers a distinctive alternative to the more common Leroy or Roy.

Deroy is likely a variant of the French name Leroy, from le roi, meaning 'the king'. As a given name, Leroy became common in English-speaking countries in the 19th century, and Deroy may have emerged as a phonetic or spelling variant. It has seen sporadic use in the United States since the early 20th century, with modest popularity in the 1930s.
