The name Lir is a boy's name . Lir.
From the experts:
Lir is the Irish god of the sea, the equivalent of the Welsh Llyr which some equate with Shakespeare's King Lear. This is one of those rare names that is simple and has a deep history with an appealing meeting and yet is completely unused in the modern world -- no baby boys were recorded as receiving the name Lir in the US last year. Maybe because it sounds like the unappealing leer?
