Alicia - I like it pronounced A-lee-see-uh, but i've only ever met people who pronounce it A-lee-sha so i'd probably pronounce it A-lee-sha. I used to watch a show (no idea what it was, but it was about severel different girls in america and shown on Trouble TV - oh they were the days) where there was an
Alicia pronounced A-lee-see-uh and I've loved it since
I know 3 (all 23) and they spell it
Alicia and pronounce it A-lee-sha. I wouldn't say it's common since i've never come across anybody else with the name, bar these 3 who happened to all be in the same school year.
I think its one of those names where to get it they way you want the child will have to tell people and correct people on how to say it
I'd go with
Alice, then
Alicia and then
Alyssa but I like all three
