Hi, I have just got a 1703 document for Malcalf that may be connected to yours. It is for moeity of a half of 2 bayes of buildings used as a barn at Malcaffe in the parish of Chappel en le Frith, also for parts of closes of land called Great Marshfield, Little Marshfield. The people concerened are John Fryth, Samuel his son, William Oldfield & William Walker all of Peake Forest, Derbyshire. I have looked on Google and there is a farm called Malcoff Farm and a peak called Malcoff nearby. The location appears to be as Ray T states, to be precise it is on the road from Slackhall, north north west and on the bend at the top of the road. The barn is probably the same one as in my document. Chris
