Gaelic- From the pool, laughter.



Boy:

Isaac or it could be Isaack, Isaak, Isac, Isack, Izaac, Izaack, Izak Hebrew- He will laugh, Laughter, God smiles.
For a boy, Issac means laughter. For a girls name I couldn't find one that meant "laughter" but Sarina is kinda pretty and it means "Princess, or One who laughs."
