Maybe Susan was born there. This was one comment under the video of the hospital.
"The village was a Psychiatric hospital, the main hospital quarter mile up the road l would have been where you were born, I was born there in 72, my Family worked there for many years."
And another comment "Hard to believe it's been nearly 25 years since bangour village hospital closed and replaced by St. John's hospital. There was talk of the village being redeveloped as a housing scheme but obviously still not happened. Tragic to see as some of the buildings were beautiful"
