I dont think so! I think maybe [name]Rocco[/name] and [name]Cole[/name] are a little similar because of the “co” sound, but if you like the names i wouldnt let that deter you. they dont sound that similar. and [name]Cole[/name] and [name]Leo[/name] is cute! I knew brothers named [name]Ryan[/name] and [name]Bryan[/name]…now that is too similar!!!
I don’t think most people would notice the coal and rock thing. It would bother me, but the average person wouldn’t care. I don’t like how [name]Rocco[/name] and [name]Cole[/name] both have the ‘co’ sound, but if that doesn’t bother you, than use it. I like [name]Leo[/name] and [name]Cole[/name] together, I didn’t notice the whole letter thing. Either way, it doesn’t matter what other people think, it’s what you think sound good together.
[name]Cole[/name], [name]Leo[/name] and [name]Rocco[/name] are too similar for my comfort level but I may be overly sensitive to sounds and the way names look together. Many people aren’t as picky.
FYI - [name]Rocco[/name] may sound like “rock” when you pronounce it but it doesn’t mean “rock”. It means “rest”.
