Debating a 3rd but need help finishing sibset of names

Name Advice
1

Debating having a 3rd has gotten me thinking about baby names already. Big brothers are:

[name_m]Alexander[/name_m] “[name_m]Xander[/name_m]”
[name_m]William[/name_m] “[name_m]Liam[/name_m]”

I need a boy and girl name that has a diminutive short form that goes well with big brothers’. Both bothers go exclusively by the diminutive short form of their name and that derives from the long form’s ending, see it… [name_m]AleXANDER[/name_m] and [name_m]WilLIAM[/name_m]. I’d like to keep the trend of using the ending of the name and long form and short form / nickname having same meaning, but not totally necessary. [name_m]Just[/name_m] no pet name… Real nicknames that could theoretically stand alone please.
