I think too much is made sometimes about variations in spelling of names. The fact is that up until relatively recently (say, the last 100 years or so), any spelling that conveyed the desired pronunciation was just as valid as any other. Witness the fact that in some documents, the same person's name is sometime found in more than one spelling! Obviously, the person writing the document did not care. Add in the fact that many of the people we are researching were illiterate, and knew nothing at all about spelling. I think the fact that we find prevalent spellings ending in -ot in Acadia, and the same names often changed to -eau or -eaux in Louisiana, reflects nothing more than a change in fashion in what clerks in one area or another took to be "usual" spellings of a particular sound. The clerks themselves would probably have said that since the pronunciations are the same, it made no diffrence. I don't think a search for the transition would be likely to yield much, as no transition as such ever happened. George Friedman
