Many thanks Folks. I'll get to the burials info at Hawick. It's more than likely that there was never a headstone at Yetholm
Cauther Lassie: Yes the John Jack and wife Margaret Bell are the family that Helen Stewart lived with in 1851 (Census), and are my ggg-grandparents:
John Jack (44, general labourer) and wife Margaret (42) living at Middlemostwalls, Sprouston, Rox., with children Janet (17, farm servant), Jane (16, farm servant), Helen (11, Helen Stewart, illegitimate daughter of Agnes Jack, reputed father: Andrew Stewart), John (9), Margaret (7), Isobella (2). Also Janet Bell (76, mother-in-law, widow, former farm servant, born in Gordon, Berwickshire).
From the RCE death record:
Helen Stewart Jack (33, “sister” and cousin of John Jack jnr) died 10 June at her mother’s (by then Agnes Whilans) home at Cessford Cottages, Eckford, Rox,. Cause of death: injuries sustained in consequence of her clothes having caught fire; no medical attention. Buried in Yetholm Churchyard.
The mystery is that my late grandparents in Hawick visited Yetholm Churchyard for some reason - and I thought it must be a Jack connection as my gran's mother was a Jack.
So that's the story.
Thanks again for your help.
Jim
