Considering Initials & Sound:

To avoid repetition or awkward alliteration, we should consider the sounds and initials. Names starting with "C," "J," or names with a similar sound to "Caleb" or "John" should be avoided or used sparingly. The surname "Sauer" has a hard "S" sound, so names with softer sounds might create a better balance.
