Think we will be going with Isaac if baby is a boy - my only reservation is it is very popular at the moment but dp is not being swayed by any of my 'weird' suggestions (Amos, Idris...) We like middle names to be family names but can't really find a family name that goes with Isaac. Main options at the moment:
Isaac Andrew (name on both sides, my grandfather who I never met, dp's father's middle name)
Isaac Nathaniel (I liked Nathaniel for a first name and it is apparently a family name way back on dp's side but much more tenuous connection)
Also considered but probably less in the running:
Isaac Hayden
Isaac James (too much mixing of old and new testament according to dp!)
Isaac Ernest (dp thinks a bit silly!)
At the moment I am swaying towards Isaac Nathaniel as think it sounds nicer but Andrew is probably a more meaningful name to me. Opinions gratefully received!
