Does this name flow?
Put a first name with a surname and see how they sit together. Nothing here is a rule; it points out the things people notice.
What it checks
Syllables come from the CMU Pronouncing Dictionary where it knows the name, and from the spelling otherwise. Names whose first name ends with the same sound the surname starts with tend to run together when spoken (“Ella Allen”); rhyming or alliterating pairs are memorable but some people find them cute. Initials are checked against a short list of words people would rather not monogram.
