How does these sound?

Okay I’ve came up with some siblings name but only first names for now and I want your guys input. So how do these sound?

 [name_f]Seraphina[/name_f] and McKenna 

  [name_m]Tobias[/name_m] and [name_m]Anton[/name_m]

  McKenna and Anton/Tobias(i haven't decided)

So what do you guys think too matchy or not enough match?

I actually think they don’t seem very related at all. I’m sorry. [name_f]Seraphina[/name_f] and [name_m]Tobias[/name_m] seem more related to me than McKenna and [name_m]Anton[/name_m].

[name_m]Tobias[/name_m] and [name_m]Anton[/name_m] work well together, as does McKenna and [name_m]Tobias[/name_m] / [name_m]Anton[/name_m]. [name_f]Seraphina[/name_f] and McKenna seem mismatched, but I guess it depends on whether you care about that sort of thing. I’m personally fine with it.

[name_m]Tobias[/name_m] and [name_m]Anton[/name_m] are great!!

McKenna and [name_f]Seraphina[/name_f] are both nice names but a little mismatched if that worries you

McKenna and [name_m]Anton[/name_m] are nice

[name_f]Seraphina[/name_f] & McKenna- [name_f]Seraphina[/name_f] and McKenna are both lovely names but, when they’re paired together, I feel like [name_f]Seraphina[/name_f] outshines McKenna. However, I do think you’re on to something! I love the idea of pairing a soft “s” name with the crisp sound of a hard “k” name (ex. [name_f]Seraphina[/name_f] & Kingsley) because I think it makes the pairing sound super fresh and elegant.
[name_m]Tobias[/name_m] & [name_m]Anton[/name_m]- This is a strong pairing. I like it.
McKenna & Anton/Tobias- [name_m]Tobias[/name_m] and McKenna sound great together. They both have a very strong, down to earth feel to them. Not a fan of McKenna & [name_m]Anton[/name_m] -not exactly sure why.
