Yes, these names are all silly, but they were said in scripted, Gravity Falls episodes. A lot of what Alex says on his Twitter is kind of intended to be a joke- the Blerble comment came with another tweet stating the Author was Geordi La Forge from Star Trek. Do we just assume that everything that guy says on his Twitter is just canon? I don't think canonicity can really be as simple as "Alex's word is God." If they refer to Wendy's middle name as Blerble in an episode, then yes, by all means that's her name. But a harmless tweet can't be enough to back that up.

Just my two cents.
