I like it! I think they work very well together – all classic Old Testament names that are very well-known but not super common. Plus the symmetry of all being six letters.
[name_f][/name_f]If I were to add to the sibset I would add [name_f]Esther[/name_f] or [name_m]Joseph[/name_m]. [name_m]Daniel[/name_m], [name_m]Samuel[/name_m], [name_f]Hannah[/name_f], [name_m]Joshua[/name_m], [name_f]Judith[/name_f], [name_m]Nathan[/name_m], and [name_m]Tobias[/name_m] also come to mind as other six letter options. Also [name_f]Ruth[/name_f], [name_m]Aaron[/name_m], [name_f]Eve[/name_f], [name_m]Solomon[/name_m], [name_m]Joel[/name_m], [name_f]Naomi[/name_f], [name_m]Phineas[/name_m], and [name_f]Rebecca[/name_f], for similar names of other lengths.
