Middle name help needed

My husband and I have narrowed down our list of favorites, but are having a hard time coming up with the perfect middle names. Any suggestions. For girls, we like [name]Charlotte[/name] and [name]Lillian[/name] ([name]Lily[/name]). And for a boy, we like [name]Owen[/name]. Our last name is Rumely, pronounced Rum-lee. Any ideas?

For a girl, going with the names of [name]Charlotte[/name] or [name]Lillian[/name], I’d go with a one syllable middle name. Some suggestions: [name]Maeve[/name], [name]Claire[/name], [name]Paige[/name], [name]Cate[/name], [name]Jane[/name], [name]Ruth[/name], [name]Tess[/name], [name]Belle[/name], [name]Quinn[/name], [name]Skye[/name].
I personally really like [name]Charlotte[/name] [name]Maeve[/name] Rumley or [name]Lillian[/name] [name]Claire[/name] Rumley.

With [name]Owen[/name], I thought [name]Benjamin[/name] first, but they kind of have the same ending. I think a three syllable name would work best.
Some other suggestions: [name]Sebastian[/name] (again the similiar ending), [name]Gabriel[/name], [name]Josiah[/name], [name]Dominic[/name].
I like [name]Owen[/name] [name]Gabriel[/name].
