Can you suggest some boy names for my baby?

I'm only 16 weeks pregnant and do not know the sex yet, but if it's a girl my husband and I have plenty of names picked out. However, we are having problems coming up with boy names we like. The middle name will be Michael and that is not changing as it's my husband's first name.

We both like more traditional names and no crazy spellings. His sister already has a son named Alexander and his brother's name is Christopher. Our fathers' names are Joseph and Robert. We don't want to use any of those names.

We kind of like Andrew Michael, but we also want some other options.
