Thanks so much for all the replies!

I have thought of Imogen as a middle name before, cause I couldn't picture really using it. But now I'm really loving it as a first name

And not just a GP or something <3 Imogen Eliza is one of my favs, they seem to nice together! Yet, the flow is off, isn't it? I still love it best, haha!
Laura is kind of dated, but for whatever reason, I still really like it! I've thought of Lauren, which seems much more dated than Laura. And Laurel sounds funny every time I try to say it :x It's just like Rory, I can't say it! Me and my poor articulation... D: I think I like Laura Cadence best, but the styles seem sooo off!
Evelyn Rose
could work, but I mainly want Rose to be a first name if anything (: It sounds too much like a filler name as a middle name... Rosalie is okay, I really do think it's pretty. But I kinda like just plain Rose haha! Rose Anneliese is my favorite, I think <3
Taylor is more last namey to me, LOL. I like Tahlia just like this

I have some form of extended family member who named their little girl Taeler Teighlor or something odd of the sort

Not sure what I like as a middle name though. Tahlia Maeve is okay, as is Tahlia Rose. Everythings just okay lol
Blake Elias and Blake Tobias are both handsome, I kinda really like them! (: Blake Matteo is okay, but I prefer Matthias to Matteo <3
As for Ronan, I read somewhere that it was like, Irish for baby seal or something and thought that was soooo adorable!

I like the sound, the look and the feel, plus the meaning~ Ronan Jack just might be my top pick- for now <3
Not sure where I found Sirius, but I haven't read Harry Potter so I wouldn't know it was there <3 I like it, for now lol. Who knows what I'll think a minute from now, haha!
And I think Theodore Callum is my fav for now~ I like it! <3
Thanks so much~ <3
