Herbert Hughes

Can anyone help me find the location of Herbert Hughes’s diaries and journals, specifically his original field notes/notebooks from his Irish folksong-collecting trips. In particular, the material relating to ‘Irish Country Songs Volume 4 – 1936). Some of this material was collected in South Kerry.

A gentleman by the name of Christopher Orr gave a talk which was shown on Youtube I think, a few years back, about the song ‘She moved through the fair’. In his talk he refers to Herbert Hughes and as far as I can gather, he may be related. The information he had makes me think he had access to the field notes of Herbert Hughes. Does anyone have a contact address or number for Christopher Orr?

Please share with anyone who might be able to help.

Many thanks.
