I don't think that the names look good together at all. I don't like
Farley for a girl. I would prefer to see Farleigh, but I just dislike the way it looks. I don't particularly like
Cambria either (Cambrian period, Coheed &
Cambria .... just too many associations with that). If I were to pick though, I would stick with
Cambria and find something other than
Farley.
I am really bad at coming up with middle names so I'll leave that to everyone else.
