For a number of reasons I always had the idea that Florida Hispanics are very euro. First, because Cubans and Puerto Ricans are very euro, and also because many upper-class white Latinos go there. Here a new study of Miami

2.2. Global Genetic Ancestry and Association with Prognosis
To estimate the global ancestral structure of this cohort, patients were genotyped and compared to West African, East Asian, European, and Native American reference populations. White non-Latino patients clustered closely with the European reference samples, whereas Latino patients demonstrated contributions from European, West African, and Native American reference samples (Figure 1B). The UM cohort exhibited considerable genomic diversity (Figure 1C). Mean percentage of European ancestry (by self-reported ethnicity or race) was 96.8% (white non-Latino), 80.0% (Latino), 30.5% (black), and 10.9% (Asian). Latino and black patients showed a range of genetic admixture, including variable European ancestry (Figure 2A). Notably, 22.2% of white non-Latino patients had >5% genetic contribution from non-European ancestry. Latino patients demonstrated the greatest genetic complexity, with 65.5% of patients having >10% non-European ancestry, mostly West African and Native American (Supplementary Table S1).
