Eulalia f. Ancient Greek εὖ 'good, well' + Ancient Greek λαλιά 'speech, form of talking, dialect'.

The name of two 4th C Spanish martyrs (who may possibly be identical with each other).

Cf. also Hilaria; these two names shared many spellings in medieval England, and are thus often impossible to distinguish in some contexts.
