Dylann

Dylann is a modern variant spelling of the name Dylan. The original name Dylan comes from Welsh mythology, where Dylan ail Don was a god or hero associated with the sea. The name's etymology is derived from the Welsh elements 'dy' (great) and 'llanw' (tide, flow). While traditionally a male name, the variant spelling Dylann, particularly with the double 'n', has seen some usage for females, especially in North America, possibly influenced by similar-sounding names or a desire for a unique spelling.

The popularity of Dylan as a male name surged in the latter half of the 20th century, largely due to Welsh poet Dylan Thomas and later musician Bob Dylan (who adopted the name). The variant Dylann emerged as a less common, often feminized, spelling, though it is still predominantly used for males. Its usage reflects a trend of altering traditional spellings to create distinct identities.
