Meaning & origin

Sennie is a rare name that first appeared in U.S. records in 1891, the same year it reached its peak usage. Since then, it has maintained a stable but negligible presence, never gaining widespread popularity. The name's scarcity means it has no recorded top states, and its trajectory remains flat over the 20th and 21st centuries. Given its obscurity, parents considering Sennie should be aware that it is one of the more unusual choices from the 1890s, with minimal modern revival.

Sennie is a rare name that first appeared in the United States in the 1890s. It may be a shortened form of Serena, which derives from the Latin serenus meaning 'clear, tranquil', or it could be an English variant of the Irish name Sena. Its usage has remained extremely low since the 19th century.
