Maude/Maud is one of those names that I adore, but neither spelling looks quite right to me.
[name_f][/name_f]I love [name_f]Maud[/name_f] because of [name_f]Lucy[/name_f] [name_f]Maud[/name_f] [name_m]Montgomery[/name_m] (obviously, considering my profile picture!), but [name_f]Maude[/name_f] looks more complete to me.
