About the name
Roisin is ros (rose) with the Irish diminutive -in, and it is pronounced roh-SHEEN rather than the way the spelling suggests to English readers. Roisin Dubh, the dark little rose, is an old allegorical name for Ireland itself, which gives the name a political weight most flower names never carry.
It is common in Ireland and among the Irish diaspora but has never entered the US top 1000, largely because the spelling and the sound part company so completely.
The pronunciation gap is the main thing to weigh. Two syllables pair well with two or three (Roisin Maeve, Roisin Delaney). On our vibe map it is Heirloom, with Vintage Elegant behind it.
