To be the male half of my stepmum’s twins
Brother to [name]Riley[/name] [name]Anne[/name] and [name]Charlotte[/name] and twin sister to be : [name]Amelia[/name], [name]Evelyn[/name], [name]Madeleine[/name], [name]Elizabeth[/name], or [name]Lily[/name]/[name]Lillie[/name]
[name]Bennett[/name]
[name]Oliver[/name]
[name]Henry[/name]
[name]John[/name]
[name]William[/name]
[name]Luke[/name]
[name]Matthew[/name]
[name]Alexander[/name]
[name]Andrew[/name]
I vote for [name]Luke[/name], [name]Henry[/name], or [name]Andrew[/name], depending on what the other twin’s name turns out to be. I like [name]Luke[/name] or [name]Henry[/name] for a pairing with most of the names, but either one of those with [name]Lily[/name] seems a little too matchy, so I’d choose [name]Andrew[/name] if it ends up being [name]Lily[/name]. Those just seem to go together to me. I love [name]Oliver[/name], but it seems to matchy with most of the twin’s name possibilities, especially if he’s called [name]Ollie[/name].
Thanks [name]Cathey[/name]. Although, we would never use [name]Ollie[/name], [name]Jackie[/name] HATES it for some reason. The same way we’re not allowed to call [name]Charlotte[/name] by [name]Charlie[/name] or anything but [name]Charlotte[/name].
[name]Amelia[/name] & [name]Alexander[/name] (I know they share first initials but I think the names are distinctive enough that the connection would be rather sweet).
[name]Evelyn[/name] & [name]Oliver[/name]
[name]Madeleine[/name] & [name]Bennett[/name]
[name]Elizabeth[/name] & [name]Andrew[/name]
[name]Lily[/name]/[name]Lillie[/name] & [name]Matthew[/name]
[name]Lily[/name] and [name]Bennett[/name]
I think sisters [name]Riley[/name], [name]Charlotte[/name], and [name]Amelia[/name] would be smashing!
Now, onto brothers. With [name]Amelia[/name], I like:
[name]Henry[/name]
[name]John[/name]
[name]Matthew[/name]
[name]Andrew[/name]
Of your list, I like [name]Andrew[/name] the best.
[name]One[/name] I would avoid personally would be [name]Bennett[/name], because of the similarity in the ending to [name]Charlotte[/name]. Might not seem like a big deal now, but when names are being called across the house, it will. Speaking from experience…my name is [name]Ellen[/name] and my youngest brother’s name is [name]Colin[/name]. It happens all the time!
[name]Henry[/name] & [name]Amelia[/name]
[name]William[/name] & [name]Evelyn[/name]
[name]John[/name] & [name]Elizabeth[/name] (I just love the simplicity of [name]John[/name], and [name]Elizabeth[/name] is classic & lovely)
[name]Oliver[/name] & [name]Lily[/name]
[name]Hope[/name] this helps!! Best of luck 
Also, I [name]LOVE[/name] [name]Madeleine[/name], but not the crazy amount of little Maddies these days. If she’s to be called by her full name like [name]Charlotte[/name], I think [name]Madeleine[/name] would be very refreshing
[name]Madeleine[/name] & [name]William[/name] or [name]Madeleine[/name] & [name]Andrew[/name]
[name]Madeleine[/name] and [name]Oliver[/name] I know some siblings with these names, and it really works for me.
1 [name]Amelia[/name] and [name]Oliver[/name]
2 [name]Elizabeth[/name] and [name]Alexander[/name]
3 [name]Madeleine[/name] and [name]Henry[/name]
4 [name]Evelyn[/name] and [name]Bennett[/name]
5 [name]Lily[/name] and [name]John[/name]
[name]Bennett[/name] or [name]Henry[/name]! I’m leaning more towards [name]Henry[/name] because [name]Bennett[/name] and [name]Charlotte[/name] are pretty close.
