Tamia
when i investigated the writing credits for "Falling For You" in ASCAP, they had her listed as "Tamia Washington", so we may want to update that as "real name". allmusic listed her full name as tamia washington as well.
however, i'm not sure what your policy is for female writers who end up marrying. she may have written these songs as tamia washington, but she has since married American NBA star Grant Hill. don't know how she signs her name - whether she has adopted his surname or not. i found an ascap listing for one song she co-wrote post-marriage, and it still listed her as tamia washington.
