I'm aware of (multitudinous) related, similar questions concerning this, but I still feel tentative for the following example. I also referenced http://www.quickanddirtytips.com/education/grammar/oddness-when-you-start-a-sentence-with-there-is?page=1. Predicated on these, I'd guess that
"there are happiness and joy" is correct,
and "there is happiness and joy" is wrong.
Here, there is (I know why it's NOT there are here) a compound subject containing two nouns, thus the verb must be conjugated for a plural subject.
Yet Google Ngram contradicts this significantly? Why? I fear that I misconstrued something?
