Yes, Hosanna is a name. It’s usually spelled Osanna (Italian) or Osanne (French), and it’s also found as a French surname (Ozanne). There’s also the medieval English spelling of Osenna (although Osanna and Osanne were more popular). In Montenegro, it’s Ozana. The Hebrew is something like Hoshana.
First, it’s the name of a saintly Saxon princess, Osana or Osanna, of the same royal family as Osred, Oswyth, etc. (So it might not have any relation to “hosanna,” or it might be a deliberate pun.)
The main story about her is from Giraldus Cambrensis (several hundred years later), which just says it was a very bad idea for a priest’s concubine to sit on her tomb in church like it was a bench. Married priests were a thing in the pre-Augustine of Canterbury English church; but concubinage was naughty even then. So the date of the story and marital status of the woman and priest kinda make a difference to how you interpret the story.
In many Catholic countries, it has been the custom to give a baptismal name to babies after their day of birth (or the day they were found, if they were abandoned or adopted), if that day is a saint’s day or a holy day.
Apparently, in medieval France, babies born on Palm Sunday were sometimes given the name Osanna, which was the medieval spelling of Hosanna. (Because Jesus was welcomed into Jerusalem with palm branches and shouts of “Hosanna to the Son of David!”)
The name seems to have been used in England only during the 1200’s and 1300’s, and never really caught on. It was more popular in France.
Here’s an Irish legal case dealing with piracy and stealing a whole ship, in which Osanna Berrechoun, one of the French/Breton shipowners, had her case for getting the ship back jeopardized, because people in Dundalk, Dublin, and Wales mistook her given name for “Susanna.”
In Italy in the 1400’s, a woman with the given name Osanna Andreasi became famous for her visions and locutions (starting at age five) and her stigmata (in the form of swellings not wounds, and received at age 30). Her dad’s noble family was Hungarian, and her mom was a Gonzaga. She was born on January 17, so presumably she wasn’t named that because of Palm Sunday.
Osanna longed to study theology but her father forbid her; so she was miraculously taught to read, and then the Virgin Mary taught her theology in a long series of visions. At the age of 14 (which was considered just barely adulthood for apprenticeship purposes, although one didn’t have full rights for contracts), she took the first set of vows as a Third Order Dominican, took the habit, and then told her dad about it… or rather, she said she had made _a_ vow to wear the habit until she had accomplished what else she had vowed to do. Um. Yeah. Technically true….
Both her parents died young and left a lot of kids, so she acted as mother and father to them until all of them came of age, when she was 37. (At that time, she finally felt able to leave home in good conscience and join a convent of 3rd Order Dominican ladies; and she took final vows.) She also took care of all the family business until the oldest of her brothers came of age. Her cousin Federico I Gonzaga, the duke of Mantua, put her in charge of looking after his wife and kids while he was away at the wars. His son, Francesco II Gonzaga (who became duke), and his famous wife Isabella d’Este from Ferrara, also thought highly of her, and took her counsel on religious matters and affairs of state, as well as relying on her prophetic gifts. (Isabella’s dad was a supporter of Lucia Brocadelli, St. Lucia of Narni, and Isabella was sorry that she never got to take Osanna to meet Lucia.)
We have TWO contemporary biographies of her: Beatae Osannae Mantuanae by Sylvester of Ferrara (1505, in Latin); and Libretto de la Vita e Transito (1507, in Tuscan), by Girolamo de Monte Oliveto, one of her close associates. He also wrote a book of Colloqui between them about spiritual subjects, as well as preserving her letters.
(Her house is also open for tours! Scroll down for pics.There’s a museum and garden there, too. They have the surviving bits of her habit on display as relics, and that is one nicely fitted and constructed bodice. Niiiice. Costumers, take note. But boy, her arms were tiny, probably thanks to her ascetic practices, unless that’s a habit saved from her girlhood.)
Bl. Osanna of Mantua died in 1505. Her incorrupt body is in Mantua’s cathedral of St. Peter. Her memorial day is on June 18. (She was made a venerable in 1515, according to Isabella d’Este’s request; and she was beatified in 1694.)
There’s another famous blessed by the same name — Blessed Osanna of Cattaro, aka Bl. Ozana of Kotor. This lady was from a remote part of Montenegro or Slovenia, and her given name was Katarina (because she was born on St. Catherine’s Day). Her background in older books in English is presented as being just from back in the waybacks… but she was actually from a married Orthodox priest’s family, the Kozics; and her uncle was an Orthodox monk who became bishop of Zeta. She longed for more, and spent a lot of time praying while shepherding her family’s flocks.
Her father, Fr. Pero Kozic, died early when she was 14; and she felt that God wanted to her to go to the big port city of Kotor (owned by Venice, and under the Patriarchate of Venice), where she could “pray better.” Her mother let her go, and she became a houseservant to earn her bread. She came home to Catholicism and learned to read and write. She used her spare means to help the poor. She wanted even more, and became an anchoress. At age 21, after an earthquake destroyed her first anchorhold, she moved to another and became a Dominican nun, and took Osanna as her religious name (after Osanna of Mantua). So many women were interested in joining her that a new Dominican convent was built next to her new anchorhold’s church, and she was their founder without ever setting eye on the convent itself.
She ended up using her prayers for fighting plague; and she was once asked by her bishop to give a speech, successfully urging everyone to defend Kotor from an Ottoman armada.
She died on April 27, 1565, and was beatified in 1927. In 1930, when her body was moved to a new tomb, her body was found incorrupt and flexible of joints, with perfect hands and fingernails, although her feet were totally gone. (Possibly somebody had stolen/collected her feet as relics, at some point in the centuries.) Her day is April 27.
Finally, there’s also the French surname “Ozanam,” which originally was the Jewish surname “Hosannam.”
Blessed Frederic Ozanam, a professor at the Sorbonne, was one of the founders of the Society of St. Vincent de Paul, in 1833. He was a layman, who married Amelie Soulacroix in 1841, and became the father of Marie Ozanam in 1845. He died in 1853. A book by Ozanam about medieval Franciscan poets.
Ozanam would make a cool name for a boy, especially if you like the nickname Oz but not Oswald, Osred, etc.
If you want to use the name for a girl, Osanna or Ozana is probably better than Hosanna (because the syllable “ho” has unfortunate connotations). It might be confused with Osama, though.
