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 513th highest place in Ireland.

From Birreencorragh's main summit follow the rocky spur north on a bearing of 6 degrees for 650m before turning NE on a bearing of 56 degrees for a further 658m which will bring you to a point were you can (safely) turn SE towards Spot Ht 487 and onwards to Knockaffertagh's summit. The going is easy for the first two of these stages but as mentioned below the final descent onto the col leading to Spot Ht 487 is deceptively steep. The ascent of Knockaffertagh is relatively easy. The summit is marked by a small cairn. Descending directly south from the summit my homeward route through Gortnaheltia forest was laid clearly before me with the various twists and turns planned on the map the previous night apparently and comfortingly right where they were supposed to be. I found it necessary (upon reaching the 200m contour) to veer east for some 500 metres as the ground became excessively steep - certainly more so than the map appears to suggest. Upon reaching the valley floor it is clear that a series of crags at or around the 200m contour mark the start of a fairly precipitous drop to the valley floor (see picture). Upon reaching the desired entrance to the forest IG04847 03101 D followed the track over very soft ground for less than 100m turning right and proceeding across even softer ground for another 300m before track narrows then opens again and becomes solid. About 350m further on you reach a T-junction. From here it is about 2K to reach the lane and another 1k walk before turning west just short of Cloondaff to walk the final 1.2K back to the starting point. Please note however, that the OS map's interpretation of the track has a slight error (but one that can send you to a cul de sac adding an unnecessary 3k to your walk). Take a look at the map and follow the track starting about 450m to the east of Spot Ht 336m IG0396 02853. I actually joined this track at the t-junction mentioned above although map appears to show this as crossroad. The track continues downhill for another 300m or so to what appears on the map to be a staggered Xroad. In fact this is a straightforward Xroad. The track to the right quickly fizzles out while the track to the left appears to match the track as indicated on the map continuing straight for a few hundred metres before bending to the right. If you follow this you will end up at the cul de sac just below a treatment plant mentioned above!. Therefore, instead of turning left continue straight on - you will notice a small bridge about 150m ahead just as the track bends to the left.
Perhaps, (cognisant of map error) a better idea would be to leave a car, if permisable, at some point on the track above the offending Xroad (see csd's comment on Birrencorragh South Top) so that last 4.2k part of the walk can be avoided. Linkback:
