First Mexican Criollo

Estimados Colisteros,

On this day in 1587, Virginia Day became the first child of English parents to be born on American soil in what is now Roanoke Island in the State of North Carolina.

Is it known when the first descendant of Spanish parents was born in what is now Mexico? ... and who that child was?

Saludos,
