Quoting P.S I'm pregnant ♥:" <blockquote><b>Quoting tinana +2:</b>" if you spelled them differently you might ... [snip!] ... my grandmother who passed (lea) and the second name is correct, Sayla. As for Aria I just prefer the y, but aria is nice too"
I've never heard of Sayla, and neither has this site... http://www.behindthename.com/php/search.php?nmd=n&terms=sayla
which I've found to be pretty reliable. I could be wrong though.
If you want to use Lea for your grandma, I'd suggest a different name. Lea can be beautiful but Novalea looks strange IMO.
And Ariya with the Y to me doesn't make sense. Just my own opinions though.
