Dr Sidney Ferguson served in the 2nd world war as a Captain in the 81st West African Medical Division, in Burma, before joining the Colonial Service in Nigeria as a doctor.
From 1947 to 1952, Sidney, his wife, Olga and their two sons were posted to the hospitals of four cities, Benin, Makurdi, Kano and Sokoto, until his family had to return to England, as Olga was pregnant with their third son.
Sidney had to stay on for a further seven months, to fulfil his Government contract after handing in his notice, before he himself returned to England as a G.P in Rainhill near Liverpool.
During this time, he wrote many letters about life in Sokoto, which as well as being sympathetic and supportive in reply to her letters, also expressed his 'love' for her and his sons.
Patrick, Sidney and Olga's eldest son has transcribed his fathers letters and merged images from the B&W photos taken during the five years that the family lived in Nigeria, into the background.
