The name is a franconization of the Occitanian male name, Titoan, which is the Occitanian form of Anthony. Though it is a legitimate name with much history, especially in the regions within the Langue D’Oc, the name was not allowed official usage in France until 1987. The recent outburst in popularity may have something to do with Titouan Lamazou (b.1955) a famous contemporary French artist, sailor and children’s rights activist. In his case, Titouan is a nickname for Antoine, in his case, his Moroccan nanny had a difficult time pronouncing his name, giving him, instead the name of a Berber town which sounded similar to Antoine, Tétouan, which comes from the Berber, Titwan, meaning, “the eyes.” There is a district in Madrid that was named in reference to the town, Tétuan.
Titouan‘s popularity is also probably a mix of the recent interest and revival of regional cultures in France: that of the Basque, Breton, Alsatian and Occitanian. This and several other Breton and Occitanian names appear in the French top 500.
As of 2010, Titouan was the 51st most popular male name in France.
An Occitanian feminine for is Titoana, and obscure French feminine form is Titouane.
