I also use Think Baby Names and Nameberry for searching specific name elements. For think baby names it's pretty straight forward it automatically gives you suggestions based on portions of names but for nameberry you go to the advanced search engine and arrange the search to your particular specifications, but it's definitely not difficult just insert the portion you want looked up in the -ending bar and click female names.
Please rate my "Names I would Use" list & "Backup Favorites" list. Feel free to rate some of my other lists too if you have the time.
