help! baby due next week and no name! names similar to alexander and Benjamin please

[Gambia]

Help! Baby is due next week and we haven't chosen a name for a boy! 
We like quite traditional boys name, middle name will be Mark and surname starts with M too, so no M names please.
 Favourites so far are Benjamin and Alexander (although feel odd using either as one is a close family member and a friend called her baby the other recently!). 
Also would be interested in hearing any nicknames for Alexander (other than Al or Alex) and Benjamin (other then Ben)
Thank you very much!

Oh, and I love Sandy as a nn for Alexander, and Benji for Benjamin.

Other nn for Alexander are Sander, Sandy and I've known a Dander too. Benjamin could also be Benj or Benji.

You could consider Benedict (too catholic? )as an alternative.

Nicknames Ali or Bennie

Other bibilical names-Joseph, Isaac, Luke, Jacob, Daniel
