Aloysuis

Meaning & origin

Aloysuis is an extremely rare spelling variant of the more familiar Aloysius, itself the Latinized form of Louis. This name was first recorded in U.S. birth data in 1914, but it never gained widespread use. Its peak year was 1927, after which its usage plateaued at a very low frequency; the data shows a stable trajectory since then, with no discernible revival. The rarity of the name is underscored by the fact that it does not appear in any top state lists, and its one-in-a-million birth probability is effectively negligible. Parents considering Aloysuis may be drawn to its distinctive spelling and vintage feel, yet the name remains an uncommon choice.

Aloysuis is a rare variant spelling of Aloysius. Aloysius is the Latinized form of Louis, via the Provençal Aloys, itself derived from the Old High German name Hluodowig, meaning 'famous warrior'. The spelling Aloysuis likely emerged in English-speaking countries as an alternate respelling, possibly influenced by the common Latin suffix -uis. Variants such as Alois, Aloys, and Aloysius have been in use since the 19th century, particularly in Catholic families honoring Saint Aloysius Gonzaga.
