Ancestry DNA

Hi Everyone,
I recently got the results of my ancestry DNA and I wanted to share the findings.

Ethnicity Estimate:
Native American—North, Central, South 37%
Southern Zacatecas
Southeastern Zacatecas
Eastern Jalisco, Aguascalientes & Western Guanajuato
Western Aguascalientes, Northern Jalisco &
Southern Zacatecas
Northwestern Jalisco
Western Aguascalientes & Southern Zacatecas
Spain 22%
France 19%
Portugal 6%
Ireland & Scotland 3%
Italy 2%
Native American—Andean 2%
Cameroon, Congo, & Southern Bantu Peoples 2%
European Jewish 2%
Senegal 1%
Northern Africa 1%
Mali 1%
Norway 1%
Basque 1%

The results named detailed areas (Zacatecas, Aguascalientes and Jalisco) where I have found the majority of my ancestors during my years of research, therefore I was happy with the results.

Two things jumped out at me, 19% France and Western Guanajuato.

Could this be a result of political maps constantly changing. I've never considered Guanajuato on familysearch as a source for my research. Also, I don't have an explanation for 19% France, other that the old kingdoms bordered each other.

Any thoughts.
