A Genealogy of the last name Odio
The Odio family originally immigrated from Italy to Cuba in the 1700's, and then made its way to Costa Rica.
This amazingly detailed 225 page synopsis of the Odio family by Emilio Obando Cairol follows the family and its descendants over a span of 300 years.
There is also a Facebook group called the "Loveable Odios" with more information on the family.
Emilio's genealogy study is above.
