Percy Alport Molteno (1861 - 1937) was a brother of Schreiner’s close friends Betty Molteno and Caroline Murray nee Molteno. Percy Molteno settled in Britain in 1886. He married Elizabeth Currie and was active in the ‘pro-Boer’ movement in Britain during the 1899-1902 South African War. His country home is the ‘Parklands’ referred to in Schreiner’s letters, and his London address was in Palace Court, also referred to in a number of letters. He was a Director of a shipping firm, and author of a number of book, including a ‘life and times’ of his father Sir John Charles Molteno; however, the link with Olive Schreiner, outside of the social connections, concerned his 1896 book on federalism in South Africa.
