it is possible that Robert Borel could be a kinsmen of Pierre Borel as I have always heard that the Borel family was originally from England. I know that Pierre was from Belguim and that Robert Borel was married to Ann Tompkins and they were from England. It is possible that the father or grandfather of Pierre Borel could have migrated from England to France/Belguim.
Also, I have heard of a legend in the Borel family of a lost inheritance in England and as the story goes, Suzanne Appoline Borel, who was the daughter of Benjamin Borel, granddaughter of Joseph Borel, and great granddaughter of Pierre and Catherine Toupard Borel, had inherited a vast inheritance from her godmother Anne Ransford of England, but no one has any information on that inheritance. could this robert borel be a connection?
