Are my kid's names weird?

[rubybenubi]

Thank the good Lord above that you are 13 because you will, most positively, change your mind on names between now and when you need them.

That does not make you indecisive; it makes you a normal teen.
The human brain does not have complete frontal lobe connections until we are in our mid-twenties.
Before that time, the brain doesn't handle the concept of outcome or consequences very well.
This is what leads teen-moms to horrible names like Dagger Maverick and Hashtag Jameson.

When you are ready to contemplate names, please keep the child's welfare in mind as the priority.
Giving a tryndy, cutesy-poo, or completely weird name might satisfy your urge to be kr8tive but it condemns your child to a lifetime of hassles and I doubt that a loving parent would really want that for his/her child.

So, here's a critique of your choices.
They're not all bad but they need work.

3 names is generally pointless especially if you intend to honor someone.
There is no room on standardized form for the 3rd name, so it is almost always forgotten by anyone except immediate family.
I suggest trimming the names down to 2.

Girls:
Prudence Coraline Grace
...Prudence combined with Coraline is rather too much but the 2-3 flow is good.
...I like the sound of Coraline Prudence better.
...I wouldn't use Prudence Grace because using two Virtue names sounds preachy/churchy
...Coraline Grace otoh is lovely, balanced, provides great nns and will age well.

Odette Leona Swan
...Swan is just plain silly as an addition to the name
...the only Odette I ever knew was nicknamed "odor-eater" after the foot product. She now goes by her middle name Celine because of the bullying.
...Odette is a nn for Oda or Odilia and both of them would be subject to the same crude jokes
...Leona Odette, tho, has a better flow, good nns, and will age very well


Boys:
Derek Berkly Caleb
...Derek is a classic name with a good nn and will age well...nice choice as a first name
...Berkly is badly misspelled; the most common and accepted spelling is Berkeley and, for those who find 3 "E"s to be to much, the usual alternate is Berkley. I suggest one of these spellings.
...So, the flow of Derek Berkley is really good and, overall, the name sounds quite distinguished
...Caleb is the oddball here; it doesn't flow with the other 2 names and sounds too harsh.
...Derek Caleb is harsh-sounding with the "K" sounds running together
...Caleb Berkley has the same problems with th "B"s running into each other
...so Derek Berkley is the best choice

Sylvester Flynn Jonas
...Sylvester is a traditional name that suffers horrible nns in today's world: Silly or Sylvester the Cat and his lisp
...Flynn works fine as a middle name rather than as a first name because of the nickname thing. Flynn-ee just sounds ridiculous and I can't think of another nn
...Jonas is rather uncommon but not weird
...Jonas Flynn is a strong, totally masculine name that will age well.

Again, this isn't meant as a slam.
At 13, I hope you have many, many years of fun in trying out name combinations.
Just remember, the child's well-being should come first.
