Sarah, Saskia or Julia.
Julia Jack sounds like a super hero!

I think the 3 syllable names flow much better with your surname. Apart from Alexandra. The 'Dra' then the 'J' are a bit hard on the tongue!

Julia Jack - Fab Fab Fab!
Francesca Jack - Nice enough but still has a bit of a sticky point in the middle.
Lucia Jack - If this will be Lucy-a then yes. If Loo-chee-a then it's sticky again!

[MrsOzz]

Sophia Jack
Emilia Jack
Eleanor Jack

I would add to your list too.
