Lots of problems here. I did some research, and Abree is both a boy's and girl's name, and has no connection to the name Abraham. Joselyn is a modern spelling variant of the traditional (and more common) Jocelyn. Likewise, but for the male name, Mitchell is a variant of Michael. Charlene doesn't work for Charles, (the more common) Georgia doesn't work for George. Erin isn't actually a female version of Aaron; they just happen to sound the same. Aaron is Hebrew, Erin is Irish. You're missing tons of other popular (perhaps easier) pairs: Anthony/Tonya, Brian/Brianna, Felix/Felicia, John/Joan, Justin/Justine, Louis/Louise, Luke/Lucy, Patrick/Patricia, Paul/Paula, Robert/Roberta, Shawn/Shawna, Stephen/Stephanie, William/Wilma, etc. I'm just going to create my own version.
