Can you help?

I am writing a history of the Dowlais Educational Settlement. This out of focus photograph may be of some of the staff of that Settlement, perhaps pre 1936. The bearded man at the back is John Dennithorne, the Warden. The person second left may be Patrick Michael Keating of Dowlais – can anyone confirm that, please, or put names to any other people in the picture?

Thanks
