There are a few of these I wouldn't count as Aiden
rhymes, the chief one being Adan
, which is the Spanish form of Adam
and is pronounced "ah-dahn". Probably some of the Adans are respellings of Aiden
, but many of them are also Hispanic babies where the name is being pronounced in the traditional Spanish way.
Madan is also a name from India
that I doubt is being pronounced like "Maiden." http://www.thehindu.com/news/national/article3419213.ece
And I would bet the parents who have named sons Maden and Madon are thinking of them as variations of Madden and don't realize they're creating confusion with "Maiden."
But it's still a remarkable total.
