Dylan is a popular name of Welsh origin, meaning son of the sea or born from the ocean. It evokes images of vast waters and powerful natural forces. Historically, Dylan was a figure in Welsh mythology, often associated with the sea. The name gained significant popularity in English-speaking countries, particularly in the US and UK, since the mid-20th century, partly due to figures like Bob Dylan. It remains a widely cherished name for boys and is occasionally used for girls.
