How to read this. A surname match means some people with that surname, in a specific study or family record, were found to share a haplogroup, most likely due to a shared patrilineal ancestor generations back. It is not proof that you personally carry that haplogroup: surnames change through adoption, remarriage, non-paternity events, and independent origin of the same name in different families. For your own confirmed haplogroup, test your DNA with our HaploAI Y-DNA/mtDNA predictor.
