Origins of surname

This name originates from marchand de gros, meaning a wholesaler. Alternatively grossier is modern French, but not old French, for 'rude' or 'uncouth'.

Early records

The name first appears in Jersey records in 1200, when the "tenementum Grosserii" on the Fief de Bellozanne was mentioned [1]. In 1309, Thomas Grossier was recorded in the Assizes Rolls as having died "at the end of the war, out of the realm". He had held 1 virgate of land of the Abbot of Bellozanne, being no doubt a part of that mentioned above. Alice La Grossere (the feminine form of Le Grossier) took possession and had appropriated the land. Also in 1309, Peter Grossier was a Sermenté for the parish of St John, thus commencing a longstanding association between that parish and the Grossier family [2]. In 1331, Guillaume Grossier was, in his turn, a Sermenté for that parish. The St John family also held land in Trinity, where Jean Grossier was buried prior to 1523. As Nicolas Grossier of St John (see genealogy below) owed pour la sépulture de Johan Grossier an annual charge of one cabot of wheat, Jean was perhaps Nicolas` younger brother or uncle.

Branches of the Grossier family of St John settled in St Mary and St Brelade, among other places. Although the surname became extinct in Jersey during the 18th century, there remain many Islanders descended from the family in female lines.
