87½ % European "German, English, and Dutch" from father & mother
12½ % Latino "Mexican" from father
Linda refers to herself as of Mexican/American descent. The question is asking about Spanish descent. The answer to that is no.
Why it is clear Linda is predominately of European descent. The Mexican culture was an influence on her when growing up, thus it is her choice to identify herself as a Mexican/American.

Linda's GREAT Grandfather was an immigrant from Europe in the middle of the 1800s and her GREAT Grandmother was a Mexican citizen. Linda's GRANDFATHER, born in the 1800s as well, was half Mexican, which means that Linda's FATHER was 25% Mexican. That makes Linda about 1/8 or 12.5% Mexican. Linda's MOTHER is completely of European descent
