It looks pretty straightforward French but some of the words are regional or slang. Obviously Noire is black, I'm guessing that noiratro may be the same as mulatto. Criole is Creole - the same language also spoken in Louisiana. It has its origins in the western Indian Ocean. You'll see that the origin of people on this document is Mozambique, India, and Criole de Maurices. Maurice - today a country - is the former French Island Colony near Madagascar and the Seychelles Islands - pretty much where the Creole language originated. A google search and subsequent google translate reveals that Malgacho is a "prefix referring to Madagascar."
