I am medical laboratory scientist.
I thought of Zebulun (a biblical character), Quetzal (a south american bird, name of a children show's dragon teacher), Artisian (an artistic person), Orrillio (a rarely used italian name), Vigo (a drama/action actor), Vance, Excalbier (King Arthur's sword, with a generation of boys named for gun manufacturer, it is on trend), Felix (a biblical character), Hendrix (famous rocker), Andrevi (italian/rusaian sounded version of andrew), Lynx (a powerful wild cat), and Xerses (Greek God). I hope these options can help you in your name search.
I know of a variant if Ardrew that just might work. That is Andrevi. It is unique for here in the states and would be a great way to honor our shared heretiage. It would also allow him with options for a nickname away from home by his peers. The nicknames could be Andy, Dre, or Drevi. Other options could include Artor ( variant of arthur), Arrick ( from norse and celtic roots, but sounds like some slavic rooted names), and Avram (a hebrew variant of Abraham). I would shy away from Actinium which is a hazardous element. I would also shy away from Arnica, due to the likely manly nickname Arnie. Here in the states girls often get teased if their name is too masculine. Augustina would go over better here. Aggie and Tina a nicknames that more femine. Atlas is one of my favorite names too. Also consider using Apollo as a boy's name. Try Annica for a girl.

I think Gideon Thomas would be a great combination. G.T. would be a great nickname.
I like Joel Hawthorne. I have a suggestion for your dilemma. Use Moira as a middle name for a girl. I like it paired with Fiona. Fiona Moira is a great option. The other possibility is to name a girl Moira with a nickname. Moira Jane (MJ or Mori). I had a name growing up that no one knew how to say or spell and would respond to any name close to the sound of mine. I hope this helps
