Lucyanna would look neater and tidier as
Luciana. I prefer
Anne to
Anna, and I don't mind hyphens much, so I'd prefer Lucy-Anne. IRL, I'd choose
Lucy on its own, with mns.
Lucyna is confusing. Is it pronounced like
Lucinda, with the D missing? Or like part of 'halLUCINAte'? I'd much prefer
Lucy or even
Lucia.
