Your post confused me a little in that I am not sure if you are looking for Quinns or Quigleys.
However, I checked John Grenham's surnames to see where Quigleys and Harkins may have lived in proximity to each other according to Griffiths.
There are just 3 townlands and they are all in Donegal.
I checked Quinn too just in case that is what you meant. There is only one townland in Donegal.
Hope this helps
