Elizabeth Aucoin, born about 1740 in Acadia, was the mother of Joseph Trahan who married Francoise Pitre on 24 June 1783 in Louisiana. 
Bona Arsenault said that the Joseph Trahan who married Francoise Pitre was "probably" the son of Jean Trahan and Marie Girouard and born about 1740. However, the 1752 census of Prince Edward Island/Isle Saint Jean by Sieur de la Roque  shows the family of Jean and Marie without a son Joseph. This, combined with the birth record from St. Martinville, obviously casts strong doubt on Arsenault's speculation.
All that is known is that Joseph Trahan, the son of Joseph Trahan and Elizabeth Aucoin, was married at St. Martin of Tours Church on 24 June 1783. It is not known when he arrived in Louisiana or from where he came. Nothing other than their names is known of his parents.
