Anastasia - do you say it as Ana-stay-zhuh or Anna-stay-zee-uh? - I love this name with the Russian pronunciation ah-nah-stah-see-yah
but in the UK the English pronunciation would make more sense, I suppose!
Elizabeth - beautiful with Alexandra (so many nn for both names!)
Adriana / Adrianna (can't decide on spelling?!) Ade-ree-arna or Ad-ree-Anna? Depending on the way you are saying Alexandra (in your accent) they are very samey!
Georgiana / Georgianna (again, spelling?) first spelling, beautiful (again some good nn options)
Josephine - Yes, love this with Alexandra
Samantha - no, seems dated.
Susannah (but we don't like Susan?) - love Susie as a nn, very sweet!
Antonia - Not keen
Penelope - Love this but for some reason I’m not keen on Penny at all
Overall favourite pairing with Alexandra would be Elizabeth!
My suggestions for you:
Alexandra & Juliet
Alexandra & Vivienne
Alexandra & Genevieve
Alexandra & Catherine
Alexandra & Helena (hel-lay-nuh pronunciation)
Alexandra & Theodora
Alexandra & Frances
Alexandra & Diana
Boys -
Benjamin - Lovely but what about Benedict?
Frederick - My favourite of your boys names
Samuel - Nice name but I don’t think it feels as elegant as Alexandra
Joseph - Same as above
Tobias - I think this is lovely with Alexandra
Evander - I’ve never heard this name but I like it! Maybe a bit of a mouthful with Alexandra though
Overall favourite pairing would be Alexandra & Frederick
My suggestions:
Alexandra & Nicholas
Alexandra & Theodore
Alexandra & Sebastian
Alexandra & William
Alexandra & Adrian
Alexandra & Henry
