Sibling names for Maeve & Angus

Both kids have god/goddess names. Both meanings are very 'strong'. Would like a name that is god/goddess, strength meaning, quirky and not common. Might be nice if I liked more 'A' name to balance all the 'M's in the family. Boy names are hard! If it were twins, I think I'd go with Freya Thistle & Graeme Hartley.
