Last Name Dilema

Sand34

Hi ! I'm not sure what last name to give the baby..I currently still use the last name I was given when I was married (which I no longer am). My maiden name means nothing to me since my father left when i was a baby and my mom had a different last name then my maiden name.. And then there's the father of this baby to be - do I use that last name even though technically we are not together.. I was thinking of using the current last name I have (which was my exhusbands last name) but that last name will have no tie in to the baby.. Any suggestions?? My last name (which is exhusband), my maiden name (which means nothing to me) or the father of this baby's last name (which I am not technically with)??
