Baby name question?

We have a name for our baby picked out. It ticks all the boxes for us and my husband and I both agree on it (the biggest obstacle of all😳) . My concern is that I’m not sure it “flows” with our oldest’s name. We are not revealing the name until the baby is born (to anyone), so here is a good example of what our kids’ names would sound like together:

Owen and Carlynn

Again, those are not the actual names since it’s so hard for us to agree on a name, that I don’t want opinions on the actual name itself. I’m hoping more for advice on how it sounds with our first child’s name, since that is my only hesitation. Are they awkward to say together? They don’t rhyme, but are they too sing-songy?

Thanks in advance! 🙏🏼

EDIT: Thank you for everyone’s responses! I’m hoping the names AREN’T too matchy... I don’t want people thinking I tried to match them..
