Help please which one goes best?
[name_m]Mark[/name_m] [name_m]Frederick[/name_m] [name_m]Lewis[/name_m]
[name_m]Marcus[/name_m] [name_m]Frederick[/name_m] [name_m]Lewis[/name_m]
[name_m]Marc[/name_m] [name_m]Frederick[/name_m] [name_m]Lewis[/name_m]??
Also has to go with [name_f]Charlotte[/name_f] and [name_f]Katie[/name_f] as siblings!! This is the only name me and hubby sort of agree on but can’t decide on the variation!
I like [name_m]Mark[/name_m]
Another vote for [name_m]Mark[/name_m]. Your girls names are beautiful and classic so I think this pairs well.
All the best!
I like [name_m]Mark[/name_m] the best. [name_m]Marcus[/name_m] is okay though.
[name_m]Mark[/name_m] is undoubtedly the best here. [name_m]Marcus[/name_m] is okay, just a little off in the combo, and [name_m]Marc[/name_m] looks unfinished.
I like the [name_m]French[/name_m] version, [name_m]Marc[/name_m]. It’s a family name for me.
I prefer [name_m]Marcus[/name_m]. [name_m]Mark[/name_m]/[name_m]Marc[/name_m] feels dated to me.
With a different last name, my choice would definitely be [name_m]Marcus[/name_m].
Unfortunately, though, [name_m]Marcus[/name_m] [name_m]Lewis[/name_m] is a bit too sing-songy and hissy.
I generally prefer [name_m]Marc[/name_m] as a nn for [name_m]Marcus[/name_m], so I guess by default I will choose [name_m]Mark[/name_m] 
Good luck! [name_m]Mark[/name_m] [name_m]Frederick[/name_m] [name_m]Lewis[/name_m] sounds great.
I think [name_m]Mark[/name_m] is the best.
One more vote for [name_m]Mark[/name_m].
I am a big fan of [name_m]Marcus[/name_m]. With the nickname mark. To me [name_m]Mark[/name_m] sounds the best with his sisters, but I like the formality of [name_m]Marcus[/name_m].
[name_m]Marc[/name_m] I read with a [name_m]French[/name_m] accent and I am not a fan of it. Especially if you are not [name_m]French[/name_m].
[name_m]Marcus[/name_m] for sure!
Definitely [name_m]Mark[/name_m]. [name_m]Marcus[/name_m] doesn’t flow as well, and doesnt fit as well with siblings. Between [name_m]Mark[/name_m] and [name_m]Marc[/name_m], [name_m]Mark[/name_m] looks nicer [name_f]IMO[/name_f] and will lead to less spelling confusion.
