In many cases the Andals intermarried with the First Men they conquered, so that even House Lannister claims at least some minor descent from the First Men. Still, the overwhelming influence on the gene pool of the continent is from the Andals, to the point that the Seven Kingdoms are often called "the Land of the Andals" by peoples in Essos (such as the Dothraki). The exceptions are the North, which the Andals never conquered and where the blood of the First Men is still strong, and Dorne, where the Andal inhabitants later intermingled with the refugees from the east.
