Researching actually the McGlashan family. Margaret McGlashan daughter of Leonard McGlashan and Helen Burn married John Jeffrey in 1851. In the 1861 census she is living at Balsusney house. In 1871 only their two children are evident on the census at Balsusney house together with their aunt Helen McGlashan and two (known) servants. So far I've not found the parents anywhere in 1871. Margaret died in 1879 (in Largo) and no death date for John Jeffrey as yet.
Anyway, my question is about Balsusney house and what it was. Just a private home? I believe there was a linen manufacturing firm connected with the name Balsusney, and I see there is a street by that name which seems to have (expensive)? houses on it.
