Peter - It was a private nursing home, but they took in unmarried pregnant girls who worked there as unpaid skivvies, for their board and lodging and then following the birth of their babies they arranged for private adoptions. I was fortunate in that they didn't have room for another skivvy when I was pregnant, in 1960, so I stayed with a family in Chorlton cum Hardy until I went into labour. I stayed 10 days with my baby and on the day I left, my baby's new parents came to get her. Fortunately she contacted me 45 years later and her father had a photographic record of her from the day they collected her to the time she contacted me, so at least I know what she looked like when she was growing up, where she lived and who her adoptive parents are.
I'm not sure if many of the married mothers knew what was going on at the home, I suspect they did as most of us unmarried girls didn't have visitors, whilst they obviously had husbands and family visiting them.
