The story of Shannyn
Shannon moved from the map of Ireland onto American birth certificates in the twentieth century, and once it was a given name the respellings followed, each changing only the unsounded second vowel: Shannan, Shannen, Shannin, Shannyn. Most of them have no history beyond the choice of a letter. This one has a bearer people know. Shannyn Sossamon played Jocelyn in A Knight's Tale, the medieval romp with a rock soundtrack, and went on to a long run of film and television work under this spelling.

the River Shannon, Ireland's longest river
Shannyn is a spelling of Shannon, which was a river's name before it was a person's. Irish tradition ties the river to Sionann, a woman of legend, and the name is often linked to the Irish sean, old; neither reading is settled. The y spelling adds nothing to either.

Fashion outlook
Shannyn sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.
