I found old maps particularly useful when I came across what, today, is known as a large farm but, originally was a hamlet with several different families at the one address - very confusing. Such a one was known as Kirthenwood Farm when I lived in Penzance yet, in church registers, I kept discovering different family names, including my own family names, at Kirthenwood (also known as Kirtonwood). Looking at the old map you can see several different residences at the same site hence the different families. My long deceased uncle remembered the area as as boy and could take me down the path from the main road in Townshend (near his grandparents' home) to the borders of Kirthenwood. Don't ignore elderly uncles (particularly those interested in the old days). Snippets of information can fill in a lot of gaps. When I was back there in 1996 we spoke to one of the residents in Townshend who told us the only part of the old hamlet still standing was one wall in the barn! He also told us about a cottage which had recently been re-roofed and when they took out all the old roof timbers they found the main beams had been cut, vertically, from one tree so that they started with the bark on one side of the tree, then used the middle planks and finished with the bark from the other side of the tree. An interesting insight into how the old homes were built in those days and how laboriously! First find your tree! Cheers Pat
