Middle name help - baby boy

AlyLynn07

We are due with baby boy #3 in 2 weeks. Trying to figure out a middle name for this guy after taking months to agree on a first name.

Both names are family names. John was my grandfather's name. I think it would mean a lot, especially to my mom,  to use this name as he doesn't have any sons to carry it on. Arthur was my husband's great uncle who also has no children and sacrificed a lot serving in the military. Both have passed away in the last few years.

Gabriel John sounds fantastic! I also like to use a name on your side assuming the child has your husbands surname. It’s nice to have both sides I think
