Eslava is Spanish. We believe the family originated in San Sebastian,Spain.Parents of Joachim Oscar were Don Miguel de Eslava and Hypolite Alexandre.Don Miguel was born abt 1752 in Mexico City, died September 17, 1823 in Mobile; he married Hypolite Alexandre on July 10, 1794.She was born June 29, 1767 in Mobile and died January 30, 1849. Hypolite was a descendant of one of the original "cassette girls" from France who came to Mobile (then part ofFrench Louisiana) in 1702 aboard d'Iberville's ship "Pelican" to become brides for the first settlers. Don Miguel was a Spanish grandee and early settler of Mobile when it was under the control of Spain.His title was "garde almacen," Treasurer and Tax Assessor. I have the name Emelise or Emmaline Cook for Joachim Oscar's wife (Mary?).Do you know anything of her family?My only info is that her parents were Nicholas Cook and Constance Baudin.
