Then there are names which will totally be optional depending on when the kid is born. Of course most of the names I found I can't pronounce to save my life, but they're all supposed to be Angelic names. Like:

[Gemini]

They're supposed to have specific dates but like I said I can't pronounce half the ones I found to save my life.

But, yeah, those would be middle names.
Because for whatever reason I'm serious about naming as many of my future children as I can with a name using the suffix 'el'. Barring some exceptions because not every name ending in 'el' means the same. For example, my name is 'Rachel' but it just means 'ewe' even though 'el' means 'God' for many other Hebrew names. Like in 'Michael' or 'Gabriel' for example.
Yeah, it's an odd fixation.
