I'm not entirely confident that these can be considered official sources. Can you try to find an official word from either Funimation (try their twitter account), the ADR Director (Colleen Clinkenbeard) or the actors themselves?
Sorry. We needed to know the birthdates of our Funimation actors. Especially if they are used for my list of actors for FanFiction stories. However, it mostly uses over 150 LA anime and live-action actors, with at least 75 Texas actors.
As Shayanomer said, ANN, IMDB and other such sites are not the best to use as sources on this wiki because they are sites that anyone can edit, thus can easily contain misleading/false information. It's often best to rely on official cast confirmations for this wiki, particularly if it is from the anime's end credits or its ADR director/actors.
