[name_f]Alexandra[/name_f] is a beautiful and regal name. I prefer the nn [name_m]Alex[/name_m], but [name_f]Lexi[/name_f] is nice. It’s just a bit popular as an independent name in the UK, where I am from. Anyway, some middle names
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Jane[/name_f]
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Dawn[/name_f]
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Ruth[/name_f]
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Chloe[/name_f]
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Cleo[/name_f]
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Sophie[/name_f]
[name_f][/name_f][name_f]Alexandra[/name_f] [name_f]Mary[/name_f]
With [name_f]Alexandra[/name_f], I think I would choose strong classic names for siblings. Names like
[name_f][/name_f][name_f]Elizabeth[/name_f], [name_f]Caroline[/name_f], [name_f]Eleanor[/name_f], [name_f]Margaret[/name_f] etc and [name_m]James[/name_m], [name_m]Edward[/name_m], [name_m]Matthew[/name_m] and [name_m]Theodore[/name_m] for boys.
