...I suppose? They're not bad names or anything like that, I just had difficulty distributing the middle names. Here, I'll lead you through my thought process a little bit. First I looked at all of the first names and middle names. I decided I really liked how Donovan William looked / sounded. This left me with Harrison & Nolan and Paul & Charles left. So I paired them up as Harrison Paul and Nolan Charles. And then "Harry" occurred to me...then "Harry Paul," and THAT is way too similar sounding to "harry palm" for my liking. So I switched the names and same up with Harrison Charles and Nolan Paul. But then I wasn't sure about the overall sound of Nolan Paul. It's not horrible by any means, but I wasn't quite sure about the similar "L" sound in both names. I said it out loud and came to the conclusion that it didn't sound too bad at all actually.
BQ: No, not at all! Why...because they all end in the same n-sound? I find it kind of cute. It's not super matchy to the point where it's cheesy or anything like that. In fact, my top three boys' names happen to be the same way: Donovan, Jason, and Gavin. :)
ETA: Donovan actually works really well with all of the three middle name options. Donovan William was just my personal favorite. Donovan Paul, Nolan Charles, and Harrison William would be pretty nice too.
