Tamzen is of Cornish origin, derived from the name Saint Tamsyne, who was believed to have been a daughter of King Arthur's sister Morgan le Fay. The name means 'from the inland sea,' reflecting its coastal origins. Tamzen gained prominence in the 19th century as it was used by the Cornish author and antiquarian Robert Hunt in his book 'Popular Romances of the West of England.' Today, it is still predominantly associated with Cornwall but has begun to appear more widely, adding a touch of distinctive charm and regional heritage to those who bear it.
"Tamzen is quite rare, with only twelve people sharing it over six decades, but there was a notable resurgence in its popularity between 1956 and 2016."
