Hanna Greally wrote a book called Birds Nest Soup sometime around 1971.
Hanna found herself committed to a Psychiatric Hospital which was not uncommon then in Ireland and to get released she had to prove she was sane.
Hanna had an indirect Shannonbridge connection in that her Grandmother Mrs Dolan once owned the pub next to Killeens (now The Bog Oak ) and also what is now Morans Shop was used as a storespace by Mrs Dolan.
Use Google to search for Birds Nest Soup and if you have a copy to give away Shannonbridge Library have a space for it.
Was there a connection between this book and One Flew Over The Cuckoo's Nest ?
