Hi there. Sorry to be replying to such an old thread!
I was born at Crowtree Lane Hospital ijn 1966. My brothers were also bord there in 1964 and 1969. We left Louth in 1973 and the hospital was either closed by then or very shortly afterwards. I don't think it was still oppen by the 1980s, certainly not as a hospital.
I'm interested in the site for personal reasons relating to my younger brother that I'd rather not share here, so I'm also keen to hear if there are any hospital records, particularly from 1969.
