[name]Do[/name] you think that repetition of similar endings among the first, middle, or last names is a problem or not?
My last name is two syllables and ends in -son. Although I probably wouldn’t use a first name that ends in -son, I do have some names that end in -n (but not -son) that I like. More specifically, two of my favorites for a boy are [name]Adrian[/name] and [name]Rowan[/name]. With those examples I don’t think that there is too much of a problem (although I would probably use a middle name with some other ending letter though).
I don’t have as many repetitive endings among the first name/middle name combos that I’ve thought of, although one that I like for a girl is [name]Isabella[/name] [name]Sophia[/name]. (I recall the authors mentioning in the section on middle name advice about how not varying the syllable number and endings can make the combo sound quite static; the example they gave was [name]Ethan[/name] [name]Aidan[/name].)
