The following notes relate to St. Brendans well
note #1561856
note #1561857
note #1561858 & 
note #1561859

3 notes are roughly located at the same spot with one several miles away. 

In addition, 5 wells have been mapped at one of the locations but all at slightly different locations. 

As such its not possible to add anything based on the note contents. Closing the above notes, and also removing the 5 wells. Will add a replacement note stating that St. Brendans Well is somewhere near the most likely spot and for it to be mapped by someone when they are at the physical location
