It was a known practice at that time to carry one’s children to the neighbouring island and seat of government for baptism but where was Joséphine born? Saint Lucia has later references to her birth and an oral history of such, as retained by the folks of the Babonneau area, but no official documentation so Martinique has claimed the birth of Joséphine on the basis of her baptism there.
De Tascher received an appointment in Martinique in 1771 but he still appears to have spent time in Saint Lucia after that as indicated in records of a 1772 wedding in Soufrière that was authorised by M. le President de Tascher. The family did spend much of their time in Saint Lucia in the town of Soufrière because they also owned an estate there that carried the same name as Joséphine’s later home outside Paris: Malmaison.
The de Tascher family seems to have severed all ties with Saint Lucia following the British attack in 1778. Returning to France, the young Joséphine met her first husband, Alexander Beauharnais, and they were married the following year. The rest of her intriguing story is widely known, while the story of her birth lives only in the local legends of Babonneau.
