Good for her family that they love Spain.
In the grand scheme of things, Spanish folks are mostly white, yes.
Also, giving all her kids Spansidh names is no big deal.
Just the tip of the iceburg.
That is generally considered an indication that the speaker is lying or distorting the truth.
The most I get are people wanting to tell me about their ski trip.
If she just stuck to the original story, which is that she was a white girl raised in a rich family in Massachussets, whose father loved Spain and Spanish culture and was fluent in the language to the degree that his children were also fluent, that would have been interesting enough to set her apart, lmao.
