Ooh, both great options that go with older siblings really well! It’s a tough call, I think personal preference goes to [name_m]Boaz[/name_m].
[name_f][/name_f]I just looked up [name_f]Bay[/name_f] (which I took for a nature name only) and discovered that it has at least one other origin:
[name_f][/name_f][name_f][/name_f]
[name_f][/name_f][name_f][/name_f]more info
[name_f][/name_f]As a submitted name on BtN [name_f][/name_f]- “Derived from the archaic Russian verb баять (bayat) meaning “to speak, to tell”, which is ultimately derived from [name_m]Church[/name_m] Slavonic bajati meaning ‘to speak, to talk, to tell, to narrate’.”
[name_f][/name_f]This adds a whole level of meaning that makes it so closely compete with [name_m]Boaz[/name_m]! I adore the option of nn [name_m]Bo[/name_m] so I’m sticking with my original vote…I think!
