There is no way to eliminate subjectivity in combining spellings. This is especially true in the girls' list, where there are many examples of spellings which are pronounced in more than one way and popular names which differ only by one vowel sound. And of course there are differences in common pronunciations between countries. In English speaking countries with rhotic accents (USA and Canada), it would not be appropriate to combine
Taylor and
Tayla. In Australia and most of England, which are non-rhotic, most people will pronounce those the same and will see them as two different spellings of the same name. And of course when one is looking at countries with other languages you are going to have even more different ideas on what spellings are pronounced the same. It would be extremely inappropriate to make exactly the same decisions on what to combine in Germany,
France, and the USA.
Maya and
Mia are normally pronounced differently in the USA. There are quite a few girls out there named Miya and Miyah. I am sure that some of the parents who use these spellings are pronouncing them like
Maya and some like
Mia. There's no way to know what the %'s are. Personally I put Miya with
Mia and Miyah with
Maya and hope it all evens out.
By the way, I personally do NOT combine
Mya and
Mia or
Myla and
Mila.
Mya goes with
Maya, not
Mia, in my combined lists.
I think both kinds of lists are needed. I think a great many expectant parents do not agree with you and see
Allison and
Alison and
Lilly and
Lily as just two different spellings of names that are really the same. And of course in everyday life people are always interacting with others who have no idea how their names are spelled, so there is no way
Lily and
Lilly could then give them "different vibes." I think expectant parents need the information that
Jackson is actually #2 when you combine it with
Jaxon,
Jaxson, etc. in order to make decisions based on their own values as to giving common vs. uncommon names.
