I've always liked the name Erin for a girl, but it sounds too masculine and is much too popular. I decided to add the -lyn part for a more feminine sound and so it decreases the popularity

This may be a form of Aaralyn, a name which has caught on a bit in the USA, possibly due to Christian singer Aaralyn (born Amanda Williams). According to her website (and other baby name sites, which may have gotten it from her website or vice-versa), Aaralyn means "with song" or "beautiful melody." I'm not sure where this comes from, though. Aaral means "students" in Tagalog -- that is the closest thing to anything resembling this name I can find. My guess is that it's a form of Aaron + the ending -lyn, probably influenced by names like Carolyn and Marilyn.
