are these names ok?

I was wondering if the names [name]Jasper[/name] [name]Theodore[/name] and [name]Elliott[/name] [name]Sebastian[/name] are ok names for boys?
I am really struggling to find middle names, but I think these sound nice.

I agree-- these are really nice combinations!

With [name]Elliott[/name] I am struggling, not sure between [name]Elliott[/name] [name]Sebastian[/name] or [name]Elliott[/name] [name]Nathaniel[/name]

[name]Jasper[/name] [name]Theodore[/name] is really nice.

I like [name]Elliott[/name] [name]Sebastian[/name] more than [name]Elliott[/name] [name]Nathaniel[/name]. It’s kind of difficult for me to end the “t” sound in [name]Elliott[/name] and then pick up the “N” sound in [name]Nathaniel[/name].

[name]Do[/name] you have any suggestions for a middle name for [name]Elliott[/name], Im not sure of [name]Sebastian[/name] as my last name ends in a “in” sound.
I want the name to be similar to [name]Theodore[/name] though.

You seem to prefer 3 syllable middles, so I guess I’ll suggest those.

Some suggestions (with the same feel as [name]Theodore[/name]):
[name]Elliott[/name] [name]Augustus[/name] (or [name]August[/name])
[name]Elliott[/name] [name]Benjamin[/name]
[name]Elliott[/name] [name]Zachary[/name]
