[name_f]Lacey[/name_f] is pretty ! It’s one of those names that is not overly popular but strong and recognizable. I have only personally known 2 Lacey/ Laci’s throughout my life . However I also strongly associate the name with [name_f]Laci[/name_f] [name_m]Peterson[/name_m] because I distinctly remember that case
I think it fits the noun theme of [name_m]August[/name_m] and [name_f]Hazel[/name_f] . While I see where people think [name_f]Lucy[/name_f] would be a better fit stylistically ( old is nee vintage classic ) I think [name_f]Lacey[/name_f] also fits the word name vibe like [name_f]Hazel[/name_f] and [name_m]August[/name_m]
I will suggest:
[name_f]Wren[/name_f]
[name_f]Laurel[/name_f]
[name_f]Mercy[/name_f]
[name_f]Fern[/name_f]
