Diary, 9 April-16 June 1900, of Morgan S. Williams of Aberpergwm House, Neath, recounting an expedition to British East Africa [now Kenya] on safari with two companions identified only as Godfrey [probably his eldest son, Godfrey Herbert Joseph Williams] and Rhys (ff. 1 verso-23 verso), together with thirty-six photographs taken on the safari (pasted in on ff. 25-60, rectos only).
The group left London on 9 April and set sail from Marseille the following day (f. 1 verso), reaching Mombasa on 28 April (f. 3 verso). They made preparations there (ff. 3 verso-6) and left on the Uganda Railway for the interior on 2 May, along with fifty-one local porters and fifteen others. From the rail head beyond Nairobi the group trekked northwards to the vicinity of Lakes Naivasha, Elementaita and Nakuru, where the three men hunted game for several days, 9-14 May (ff. 7 verso-14). The trip was cut short due to Godfrey falling ill; he and Morgan left Rhys and returned to Mombasa, sailing to Zanzibar, where Godfrey was hospitalised, and finally sailed back to Europe on 27 May (f. 20), arriving in London on 14 June (f. 23). The photographs mostly comprise various groups of Maasai people (ff. 25-32, 34-39, 43-48, 53), the group's encampments (ff. 33, 54, 59-60) and trophies including two dead rhinos (ff. 49-53, 55-58); an European appearing in three photographs is probably Williams himself (ff. 54, 56, 60). The inclusion of a photograph labelled 'Lake Baringo' (f. 42) suggests they were taken by Rhys, as the only one to continue north to that location. Also included are various memoranda and lists relating to the safari (ff. 97 verso-100) and a pencil sketch of Mt Kilimanjaro, dated 3 May (f. 100).

Some four hundred and fifty-six letters and cards, 1926-1953 (mostly 1926-1927, 1945-1947, 1949-1953), from Mary Casey (Mary Penny before 1945) to her mother Lucy Penny, containing personal and family news, together with occasional enclosures such as press cuttings and textile swatches; from October 1946, when Mary and Gerard Casey settled in Kenya, the majority of the letters are air letters.
A single letter, 15 December 1953, from Gerard Casey to Lucy is also included, as is Lucy’s correspondence with White & Co., Southampton, February-March 1947, re. transporting some of her furniture to Kenya.

Some five hundred and seventy letters, mostly air letters, 1954-1959, from Mary Casey, Timau, Kenya, to her mother Lucy Penny, containing personal and family news, and occasional enclosures such as photographs and press cuttings; together with two letters, 1959, from Gerard Casey to Lucy.

Some six hundred and eighty-one letters, mostly air letters, 1960-1965, from Mary Casey, Timau, Kenya, to her mother Lucy Penny, containing personal and family news, and occasional enclosures such as press cuttings; together with two letters, 1960, 1965, from Gerard Casey to Lucy.

Some six hundred and seventy-one air letters, letters and postcards, 1966-1977, from Mary Casey, Timau, Kenya, to her mother Lucy Penny, containing personal and family news, and occasionally enclosing letters from family and friends, photographs and press cuttings.
The enclosed correspondence comprises six letters addressed to Mary from correspondents including Katey [Grey], 1970-1971, and Peter [Powys Grey], 1974, and three to Lucy Penny, including one from Phyllis Playter, 13 February 1970. Towards the end of this period Mary and Gerard Casey were spending more time in the UK, prior to returning permanently.
