The bit of family history I have is that some of my Scot ancestors, having lost some land, got it back or bought it back by hiring out as sort of mercenaries. They were not archers. My Scot ancestors are most noted for fighting against the English for quite a while, finally at Londonberry and in the Carolinas at Kings Mountain. I have a Bodkin point handed down from my German ancestors, which wounded one of them in the thigh. My grandmother, of Scot and German ancestry, passed it on.
Yes, Pope and Young studied the old English bows found and and with the help of Ishi, went from making flat bows to rounded longbows. Then Howard Hill started making them commercially. Today, Byron Ferguson continues that tradition of longbow prowess.
Byron Ferguson brings me back off the history to modern hunting. If you have not seen him shoot, go to YouTube and search for other videos. A few months ago, down in Other Hunting, I posted some pics and links to some hunters I know and their bears and moose taken with longbow.
