I like to use family names as middle names and had decided on Alexander however I now like Elijah as a first name and I think Elijah Alexander is a bit of a tongue twister? Also have the options of George or Benjamin but would have to use both. Other useable family name William but apart from that all the family members have names of the Barry, Derek, Keith, Lionel variety so won't be using them!
So
Elijah Alexander
Elijah William
Elijah George Benjamin
Elijah Benjamin George
