DE EUROPA A LATINOAMÉRICA A TRAVÉS DE LA GENEALOGÍA GENÉTICA: ESTUDIO DE CASOS DE MIGRACIÓN DESDE IRLANDA Y ESPAÑA

Abstract

This article introduces the basic concepts of the human genome and the genetic genealogy Y- and autosomal test to complement the genealogic research. These tests are beneficial for studying the European migration to America when the documentation is minimal, especially before and during the XIX century. This article explores the case of John Denton Creamer. He migrated from London or Ireland to New York and then to Ecuador during the presidency of García Moreno to work on constructing the Trans-Andean railways. This research discovers Creamer’s Irish roots and his relationship with the Cremin family of the McCarthy clan. After introducing the genetic evolution in Latin America and Spain, this research studies the genetic group of a representative of the Guillén family established in the Aragonese Pyrenees for more than seven hundred years and its regional impact.
