De Marzan, Jean, S.M., French
Servant In Fiji
This Marist visitor passed through Melbourne on the way to Sydney on 8th September 1888. The full journey was to be from Marseilles to Fiji where he laboured zealously for several years. Jean was born in the Diocese of St Brieuc on 25th August 1867. Religious profession was made on 8th September 1888. Apparently he was posted home to France where he died on 16th July 1927. The age was 59. A pity more is not known for the records of many of these valiant Pacific missionaries. But if it were not for the research of Fr. John Hosie, Marist Historian in Sydney, much less would be known.

Fr. Jean de Marzan, d. 1927
Fiji
He was born in Côtes-d'Armor, France in 1867. After formation in England and Spain, he left for Fiji in 1893, at the age of 26. After short postings to Rotuma, Wairiki, Loreto and Solevu, he was stationed at Lomary. From here he accompanied Fr. Emmanuel Rougier up the Navua River to make the first contact with the Namosi people of the interior. He then remained in the interior, and in 1904 founded the difficult interior mission of Solo-i-ra, later known as Vanuakula, in Naitaseri. He established Catholic communities in the very interior of Viti Levu, up to the headwaters of the Wainimala River. He was a strong walker through the difficult inland regions and the local people called him "the steam train" . By 1920 he was back in Lomary mission. He died there at the age of 60.
