“Mahal” also means love in Filipino, which is why I love Mahalia. There would be a different pronunciation there, more like muh-HALL-yuh, like the Taj Mahal.
A young girl at my church has this name. Her sister's name is Melelia, pronounced "muh-lale-ee-uh", so the names are very similar. I think it's bold to name your child these names, they are unique and not many people have heard of them. Beautiful to hear though.
