Looking for a boys name!

Hi! I’m looking for a boys name to go with the girl names my fiance and I have chosen.
We aren’t pregnant but are TTC#1 and I love thinking of name combinations, but I’m struggling with boys names right now! I purposefully chose the following names to include a variation of Alexander (I don’t know why I just fell in love with them all!). Our last name will be “Bird”.

Our girl names are:
Valentina “Tina” Grace Exandria Bird
Seraphina “Sera” Aleksandra Valkyrie Bird

My top boys name right now is “Alessander Thaddeus James Bird” but I’m looking for more suggestions if anyone has any, I tend to stay away from the most popular names and I love soft sounding names with short nicknames.
Thank you so much in advance!

With [name_f]Valentina[/name_f], [name_f]Seraphina[/name_f] and Alessander, I’ll suggest…
