Thank you! I am blown away by how quickly and helpfully you replied, aghadowey and kingskerswell! aghadowey, I would be so very appreciative if you found the book and were willing to sell it me for a reasonable price (i. e., not 60 + pounds!) and of course I would pay any postage and other costs. Your area (I presume?) is quite magical, and was for my extended family (mother's generation especially, as for my grandmother's) a favourite place to visit and hike, explore, and enjoy the peaceful country.
My great aunt Dorothy loved her dairy farm and at one stage my own grandmother Grace Robertson, whose post-secondary education was cut short to care for her grandmother Jane Alexander Ritter at the Dog Leap, was possibly going to stay there to help run it. She came to Canada and studied dairy farming at the Guelph Agricultural College (now University) in Ontario, Canada at the turn of the last century but married a Coleraine (and Ballymoney) man, Cyril Benson, and lived very modestly on a farm in Nova Scotia, where she raised her children and made very good friends. (Thus we are Canadians.) Another of the Robertson sisters, Muriel, worked for decades at the Lister Institute as a protozoologist, and did ground-breaking work regarding sleeping sickness and trichomonas. The family think that EFC Ritter and Robert Andrew Robertson brought a great love of learning and inquiring spirit into the family (Alexanders). It was lovely to see the Roe Valley Country Park, including land that once was handed down from Sir Thomas Philips. I hope you will excuse my ramblings. It is fun to put some reality and context to stories I heard growing up. Thank you for your replies. Joan Robb
