Just a heads up, I had a reply from Mike about the data from Brazil (from the 2010 Census, displaying usage of names by decade) that I had sent him and basically, he's focusing on getting the latest update finished and what I had sent to him is on the todo list. I am going to assume the Mexico source is on his todo list as well.
