Alivia

While Alivia may not have achieved the megapopularity of its mother name, it's firmly in the Top 200 which means there are an awful lot of little girls with this same-but-different name. Alivia combines the trendiness of A names with the trendiness of Olivia to create a choice that's slightly off the beaten track -- slightly being the operative word here. Is the distinction the initial A earns you worth a lifetime of explaining, "No, it's Alivia, with an A, not Olivia"? Your call, though ours would be no.
