I assume SCC means I just got it off the web, which I did.
Since this thread has lead us to elephants and rhinoceros, I figure I might add:
I have always gone with that the possessive of Gross is Gross', not Gross's. As the same with even Davis'. Also I find that the "x" ending French (Cajun) names, like Boudreaux or Giroux also do not use the 's.
Just one Gross' opinion
