The First Name Alphabet is as follows:
Although it is widely agreed upon, there exist constituents of the First Name Alphabet that are disputed by some.
For example, the Military Alphabet actually does contain some first names, such as Charlie, Juliet, Mike, Oscar, and Romeo. Although some have attempted to merge these two alphabets, the general trend among users of the First Name Alphabet is to eschew all names that were present in the Military Alphabet. Therefore, these names are not a part of the First Name Alphabet.
Another point of contention revolves around the fact that Uncle represents the letter U. Some critics have complained that Uncle should be removed in favor of a "true first name" such as Ursula, Ugueth, or Ulysses. However, these names are extremely uncommon, and it could potentially take several seconds to come up with a name that starts with U. This fact, combined with the prevalence of celebrities such as Uncle Kracker, has led to the acceptance of Uncle as a viable first name under these circumstances.
Some have taken issue with the imbalance of male and female names in the first name alphabet because male names comprise 88.4% of it. The reasons for this imbalance are unclear. Due to its origins, the most common hypothesis for the lack of feminine representation in the First Name Alphabet is that finance professionals, who are more often male, simply used names of their other male colleagues. Some alphabet users likely view this as a natural occurrence while others view it as blatant discrimination. As for the reasons behind the nominal disparity, others argue that historically, many female names have been derived from male names (e.g. Olivia, Petra, Samantha), and that it would only make sense to use the original male name in this context.
