Claire, Jane, Julianne, Marie, Amanda, Cheyanne, Grace, Margaret, Katelyn, and Irene Just to name a few... I choose some more traditional names considering the first name. Hope its Helps!
It's up to you really. If you want it to be similar to faith, you could do Mercy, Grace, Hope, Light, Prudence...they're endless! Otherwise, it probably doesn't matter, as long as you like the name
