I'm seeking your opinion on how our DS1 name goes with the chosen name of our DS2. I'm paranoid they might be too similar.

DS1: Jonah Dale

DS2: Owen Gray

They both have the O sound and the first names are 2 sylable, second names 1 sylable.

We know someone who has 2 boys Oskar and Kaspar, I'm not a fan of rhyming names or choosing similar names or all having a name starting in a similar letter. Everyone has likes and dislikes, traditions which they like to follow, which I don't judge upon, I'm just not a fan. So with that in mind are these 2 names too alike?
