We had also interacted re our French ancestors (Huguenot in my case) and things "Cajunish", etc.
I had emailed him a couple of weeks ago re a Bergeron in-law of my wife's ancestors in New Orleans; his email gave no hint of his health problems. I will very greatly miss him as a most excellent (!!!!) historian and friend.
