Susan, I have just started researching the family of James F. Darch who emigrated to London, Ontario, Canada, probably in the late 1840's. In Canada he married Sarah Chick, daughter of William and Hannah, fron Yarnscombe, Devon. That is not far from High Bickington, so I am wondering if the two families knew each other before they left England. Another family associated with them is that of HerbertAshplant, who came to Canada in the 1870's and married the daughter of James and Sarah Darch. Let me know if any of this connects to your research.
