To save you the trouble of working through dozens of blogs, I have summarised my understanding. There are three groups:

  1. People for whom there is a provable, definite connection to my Grandfather Patrick Stanley
  2. People for whom there is no connection, despite sharing surnames and location
  1. People for whom a connection is yet to be proved

I have posted my DNA results on Gedmatch. The kit reference is WW2962088
