I have recently found (with the aid of Dwayne Montz, a helpful reader of these forums) baptismal records for Catherine Eulalie Goy & Marthe Pauline Goe. I believe that they were siblings. Their mother is listed as Elisabeth Goy, also Jeanne Elisabeth Goe. Her origns are given as Por-au-Prince, St Domingue or St Marc on Santo Domingo. The children were born in 1815 & 1818. Thus Elisabeth sould have been born about 1790-1800.
Elisabeth may be the widow Mimi Goy listed in the 1823 New Orleans City directory living at 6 Peace Street. I have no other information about her and would love to know more.
The baptismal sponsors are: Bernard LaFosse and Catharine Eulalie Rocheblave, Paul Prudent Audier & Martha Roup, former resident sof Santo Domingo.
