I've read theories on this, one is that jaglin comes from a well to do family called jacklin, who used to reside in purston, the theory i've read for featherstone,is that it derives from three(feath) and stone, its thought that it comes from a megolith made up of three stones possibly in the north feath area, i think its either tony lumb, or jim williams theory
Interesting. I wonder if Featherstone and Purstone are linked because of this. Take the stone off each one and you have Feather and Pur. If Feath means three, I wonder what Pur means?
