Thank you Don. That does help me. The link to the extensive series of maps will be very useful. I am familiar with some of these maps but others are new to me. The Peters are frustrating me as we know they farmed at Boclair and Baljafray and also have a rent book mentioning who paid rent at Boclair between 1730-1750, but the various christian name are so common in the family that linkage to the rentees and other Peters in the early 1700's is proving just about impossible.
Many thanks
Cec
