I’m not really feeling it for Brekon, Rylend, or Matrix. [name_f]Marabelle[/name_f] has such a classic feel to it, those boys’ names just don’t seem to fit with it. It looks like you’re going for something unique and modern with a strong sound for a boy; I think there are some good classic options (more like [name_m]Harvey[/name_m] and [name_m]Lukas[/name_m]) that would go better with sister’s name. Or, some little tweaks to the three you listed would help bring them into the same realm as [name_f]Marabelle[/name_f] [name_f]Everleigh[/name_f].
For example, [name_m]Breccan[/name_m] is the original Irish spelling of Brekon. [name_m]Breckin[/name_m] is another spelling that looks a little more classic but would probably be easier for modern spellers than either [name_m]Breccan[/name_m] or Brekon.
[name_m]Ryland[/name_m] looks a little more classic than the more modern Rylend, although they sound the same.
I can’t think of a classic analog for Matrix; it’s 100% modern and very unique. To me, it comes on a little too strong, especially side by side with [name_f]Marabelle[/name_f], which is such a sweet and lovely old-fashioned name. It’s like a black leather jacket next to a muslin dress with an empire waist.
Here are a few suggestions for more classic (or classic sounding) but still less common boys’ names:
