Two questions:
What would you name [name]Dexter[/name] and [name]Malcolm[/name]'s brother and/or sister? [name]Feel[/name] free to suggest as many as you like, I’m open to all ideas.

What do you think of [name]Dexter[/name] and [name]Malcolm[/name] as sibling names? [name]Do[/name] they go together well?
Well I love [name]Dexter[/name], must admit I’m not too keen on [name]Malcolm[/name]. Having said that, they do work well together though and the combos [name]Dexter[/name] [name]Benjamin[/name] and [name]Malcolm[/name] [name]Zachary[/name] are very handsome:)

I [name]LOVE[/name] the sibset [name]Dexter[/name] and [name]Malcolm[/name], they go perfectly together.
For a boy I would pick something like [name]Emmett[/name], [name]Findley[/name], [name]Desmond[/name], [name]Julian[/name], [name]Sebastian[/name], or [name]Graham[/name].
For a girl maybe [name]Freya[/name], [name]Iris[/name], [name]Elinor[/name], [name]Livia[/name], [name]Rosalind[/name], [name]Georgia[/name] or [name]Vivienne[/name].
I always feel more helpful suggesting what people NOT do, rather than what they SHOULD do. 
I would just steer clear of D or M names, because you don’t want [name]Malcolm[/name] to feel left out amongst [name]Dexter[/name] and [name]Desmond[/name] (or vice versa). I [name]LOVE[/name] [name]Desmond[/name] and it would go beautifully with your set, except that it’s very very similar in sound and alliterative to [name]Dexter[/name].
[name]Just[/name] using [name]Desmond[/name] as an example.
I wasn’t planning on using D or M first names. I also want to avoid -er and -m endings. I was hoping to find a two-syllable name with a nickname that was fairly uncommon, though the popularity doesn’t matter much. My favorite set so far:
[name]Dexter[/name], [name]Malcolm[/name], and [name]Simon[/name]
[name]Dexter[/name], [name]Malcolm[/name], and [name]Jonah[/name]
[name]Dexter[/name], [name]Malcolm[/name], and [name]Nathan[/name] “[name]Nate[/name]”
[name]Dexter[/name], [name]Malcolm[/name], and [name]Emmett[/name]
[name]Dexter[/name], [name]Malcolm[/name], and [name]Samuel[/name] “[name]Sam[/name]”
I think [name]Dexter[/name] [name]Benjamin[/name], [name]Malcolm[/name] [name]Zachary[/name], and [name]Samuel[/name] [name]Dominic[/name] are winning right now. :lol:
[name]LOVE[/name] your names 
[name]Dexter[/name] [name]Benjamin[/name], [name]Malcolm[/name] [name]Zachary[/name] and …
[name]Calvin[/name] [name]Samuel[/name]
[name]Everett[/name] [name]Nathaniel[/name]
[name]Stellan[/name] [name]Joshua[/name]
[name]Scarlett[/name] [name]Olivia[/name]
[name]Beatrice[/name] [name]Abigail[/name]
[name]Violet[/name] [name]Rebecca[/name]
[name]Calvin[/name] [name]Samuel[/name] - [name]Love[/name] [name]Samuel[/name], but I’m not a fan of [name]Calvin[/name]. The name itself is fine, but I don’t like the nn ‘[name]Cal[/name].’
[name]Everett[/name] [name]Nathaniel[/name] - [name]Love[/name] both names, but I would prefer them switched around to [name]Nathaniel[/name] [name]Everett[/name].
[name]Stellan[/name] [name]Joshua[/name] - I don’t really like [name]Stellan[/name]. Too close to the popular girl name [name]Stella[/name]. [name]Love[/name] [name]Joshua[/name], though.
[name]Scarlett[/name] [name]Olivia[/name] - Neither name is my style.
[name]Beatrice[/name] [name]Abigail[/name] - ditto.
[name]Violet[/name] [name]Rebecca[/name] - love both, but would prefer [name]Rebecca[/name] [name]Violet[/name].
I’m still leaning towards:
[name]Dexter[/name] [name]Benjamin[/name], [name]Malcolm[/name] [name]Zachary[/name], and _______ [name]Dominic[/name]. I love [name]Samuel[/name], but I don’t think it goes with [name]Dexter[/name] and [name]Malcolm[/name] enough. Any suggestions for _______ [name]Dominic[/name]?
[name]Isaiah[/name] [name]Dominic[/name]
[name]Nathaniel[/name] [name]Dominic[/name]
[name]Jasper[/name] [name]Dominic[/name]
[name]Archer[/name] [name]Dominic[/name]
