Towards the end of 1942, at the height of the Pacific Campaign of the Second World War, the Colonial Authority was issued a command to close all urban schools and surrender their compounds to the military, to be used as military camps for the war campaign against the Japanese threat. At that time, a notable missionary teacher by the name of Mr William Earnest Donnelly, was serving as principal of Toorak Boys’ School. Whilst other overseas teachers immediately left Fiji to await the end of the war, the determined missionary principal, Mr Donnelly sent a circular to all members of the senior classes of Classes Six, Seven, and Eight of Toorak Boys School, inviting volunteers to come away with him, to continue their education. After consultation with the heads of the Methodist Church, he was given permission to use the principal’s residence at the Davuilevu Technical School. As a result, he and 50 volunteers from Toorak Boys School in Suva, met at the principal’s residence on 3 March 1943. Their first classrooms were the two master bedrooms in the house and the long verandah on the eastern side as their library. There were only two classes and two teachers; the late Mssrs W.E Donnelly and Semesa Sikivou. In the 1943 Methodist Church Annual Conference, Mr Donnelly was given permission to expand his classes along the same ridge and as a result, the boys themselves, with his and Semesa Sikivou's guidance, built three large bures, where the teachers staff quarters presently stand. He was also directed to name the new school, Lelean Memorial School, in memory of a long serving and beloved missionary in Fiji, the ReverendCharles Oswald Lelean. Rev Lelean was an Australian missionary who served in Fiji for 36 years, from 1914 to 1934. Amongst his students were Rusiate Nayacakalou, who later became the first South Pacific Islander to graduate with a PhD and Jimione Samisoni who became the first Fijian to become the dean of the Fiji School of Medicine.
Sikivou, who hailed from Rewa Province, belonged to the tribe of the Roko Tui Dreketi's Guardians of the Spirit and the Wise Counsel, and as such was a member of the traditional court of the Paramount Chief of the Burebasaga Confederacy. He had strong ties to the Provinces of Namosi, Naitasiri, and Verata. He was married twice, first to Seini Ratuvou of the Vutia District of Rewa, with whom he had one daughter, Ateca and three sons: Navitalai, Rokocanini, and Metuisela Sikivou. His second marriage was to Salote Tabuanitoga of Kadavu Island. With her he had two sons: Jese and Mosese, and a daughter, Vasiti Sikivou-Waqa.
