Alexa and variants are so popular here, that I'm sick of it. But
Alastair/
Alistair is different enough that I still like it. But then, I can think of only 3
Alex/ Alexanders and tons of
Alexa/
Lexi/
Alexandra etc.
Since it's your like list, it's up to you. Do you still like the names? I still like
Isabelle and
Sophia, even though I'd try to keep them off of my to use list because I have a popular name and don't want my future kids to be one of many with a name.
