Sheenan

Irish surname, variation of Shannon

"old and wise"

Sheenan Origin and Meaning

The name Sheenan is a girl's name meaning "old and wise".

Sheenan updates the longtime Irish favorite Shannon, which ranked in the US Top 100 through much of the 1970s, 80s, and 90s. Shanon fell off the Top 1000 about ten years ago, but Sheenan is a worthy substitute. You might also consider it a form of Sheena, itself a form of Jane or John, with the meaning "God is gracious".
