Eachmarcach is a personal name meaning 'horse-rider'. It is the origin of the surname Mac Eachmharcaigh, which can be anglicised Cafferkey or McCafferty and is a common surname in Mayo [De Bhulbh]. It would seem that this is the most likely origin of Knockaffertagh, though an Irish form for the name has not been found to support this. The t in Knockaffertagh is not a problem as the anglicisation McCafferty shows that such a pronunciation of Eachmarcach is possible. The hill is named Ummeraufferty on William Bald's map of Co. Mayo (1830), which appears to be a similar name with Ir. iomaire, 'ridge' as the first element instead of cnoc.   Knockaffertagh is the 511th highest summit in Ireland.

A grand soft day
by JohnQ  12 Sep 2010
12/09/2010: JohnQ : walked to this top starting from bridge at Bogadoon river on R312 approx 15 miles from Castlebar ; taking Keenagh loop walk in anticlockwise direction while M& E did the loop in clockwise .After small quarry and initial climb left the loop heading up to rocky outcrop and then gradually climbing in westerly direction waiting for Birreencorragh to show . The ground is varied not too remarkable but fine views of Nephin behind to the east. A cairn marks the top , day started clear but gradually misted over and this made Bireencorragh top not visible - but it looks a real 'jag' of a mountain - sorry no pics - headed back due south which turned out to be a good bit steeper than expected - when back from under the mist fine views of valley floor M& E having the brew at lone tree on bank of river that meanders through Glendorragha valley
Rejoined on the loop walk- more coffee- great day out - we''ll be back !! Trackback: http://mountainviews.ie/summit/417/comment/6093/
