Undoubtly there were some Cathars that survived.However,these were most likely the credentes,or ordinary believers.The Perfecti,also known as Good men and Good Women died just as Questionmark posted. They were the ones who oberserved celibacy,ate no animal flesh,and preformed the various ceremonies of the Cathar faith.
Many of their books and writings are lost to us,though i think there are a few books here and there,that might have survived.However, those who knew how to preform the rituals are gone.Such is not the case with the Waldeseans,who were founded by Peter Waldo in Lyons back in the Middle Ages.They still exist and some of them came to the US and founded a town in either North or South Carolina.
You can find out information on Google or New Advent,or other places on the net.
There was also the Humiliati,I believe they still exist,but mainly as a purely regilous community.
The Italian Cathars were well known as weavers,as were the Humiliati group.
Whether or not they wove any messages in the cloth is another matter.
As far as Druids and pagans go, the question is,are they practicing the same ancient rites as their ancestors to which I answer,I don't know.
Is it possible some of them do,yes of course. They may have passed this down through the generations. Just like in Spain, jews who choose to convert and become Catholics in order to remain in Spain were known as conversos.Sometimes,they were accused by neighbors of still practicing jewish rituals in the privacy of their home.Most likely there were some families who did.
There were even Cathars in Germany,but have been able to read in English very little about them. I sometimes wonder if any of my father's relatives ever belonged to them, but I have no idea if the Cathars were in Bavaria,or what towns there. I too would like to know more about the Knights Templar in Germany,and they were there.My father's family has always been in the military in Germany,probably even back in the days when they were pagan ,and fighting Romans and other germanic tribes.Would love to know if any members were Knights Templars or Teutonic Knights. Quite possibly yes,but I'll have to save up my money and try to write relatives in Garmisch to find out which relative in Nuremberg keeps the family history book and where they live in town so I can visit them.Would love to win the Lotto so i could hire someone to do research for me.
Also I believe the Cathars rejected not the New Testament,but the Old Testament.I understand they were partial to John's Gospel. And there may have been some connection to the Bogomils, as a Bogomil bishop visited the Cathars at a confrence they group had,I believe in Italy.
