As I stated there is no documentation for the ancestry of Gervais du TREMBLAY, the only two sources of the early TREMBLAY genealogy is in the two books I mentioned. I have seen several genealogies posted on the which extend back to Bernard du TREMBLAY / du DRAMLEY (some info here) but no one posted any documentation. There are other early TREMBLAY lines but there is no connection that I know of. There is a TREMBLEY line out of Switzerland (book on that, but forget the title). If you come across anything, please let me know.
