Thanks for the lovely pic, Terry. What a good looking young man! I have a pic of John looking very stern and patriarchal, but I'm not sure my technical skills are up to posting it.
Glen, thank you for all the info you've given me. I didn't know the places where my lot lived had links with the textile industry, or that Clockmill was so close to Duns Castle. I really envy you your local knowledge!! I managed to find out a bit more about Hatchednize Farm last night, and suspect I'll be spending a lot of time on that Scottish Gazette site today.
John Service must have done well for himself as a chemical works foreman, considering he was the son of an Ag. Lab. My mum tells me they were well off enough to afford a maid; her mum's sister Elvie was brought up by her grandparents (their mother was very ill after the birth of one of the younger children) and never had to lift a finger, apparently, so it was a great shock when she married and had children of her own.
