Sheridyn is of Welsh origin, derived from the ancient personal name Sheridan, which was initially an Irish surname meaning 'from the foot of the fairy hill'. The name was popularized in England by Richard Brinsley Sheridan, a noted playwright and politician of the late 18th century. Today, Sheridyn is often considered a feminine given name, but it can also be used for boys due to its unisex nature. It's pronounced /ʃəˈrɪdən/.
"Sheridyn saw its peak popularity between 2000 and 2001 with ten and twelve births respectively, after which it began to decline steadily."
