Thirteen diaries, 1898, 1912-1919, 1922-1923, 1927 and 1930 and 11 pocket note books.
Although the entries in the diaries are sparse, a surprising amount of information can be gathered from them. There are details of chapel meetings, local events, the weather, planting of vegetables, books borrowed. The effect of the First World War comes to light as Evan T. Davies refers to Llywelyn (possibly his son) returning home from Ypres.
The note books are difficult to decipher and contain lists of books, lines of poetry, names and address and rough notes in general, written in Welsh, English and French.
