Hi Cloe ~ The 1st thing I would want to know is: Who is answering my question, & what do they know about boy's names? I have 1 son, 1 grandson, & 1 nephew. I am partial to strong, solid names, that a boy & a man, can use w/out ridicule.I am partial to Michael, Ryder, Tyler, & Robert; but w/your last name, I like Alexander James the best.Alex is a strong male name, w/little room for ridicule. "Alex & AJ," are both Strong, Solid nicknames.Alexander James, AJ or Alex J. Billowitz; all roll off your tongue; but Jack doesn't - it sounds harsh. ~ So, this is my opinion; but it is Your Opinion that counts; you are his "Momma!".~ My Best Advice is for you to Listen to your "Gut feel." ~ I believe, if you listen to that "Small, Still, Quiet Nudging," it will always guide you correctly - on Everything!Your son has an "intended name." ~ Listen, Trust, & you will know! ~ Good Luck & God Bless!
