The surname Karra (కర్ర) is not exclusive to a single caste in Andhra Pradesh. It appears across several communities, reflecting the complex social fabric of the region.
In coastal Andhra districts (Godavari, Krishna, Guntur), Karra is more common among Kapu and Kamma families. In Rayalaseema, it appears among Reddy and Velama lineages. The surname also exists in Karnataka and Tamil Nadu, where it's typically associated with Kapu/Reddy migrants from Andhra.
Surname-caste correlations in South India are probabilistic, not deterministic. Migration, intermarriage, adoption, and Sanskritization have blurred historical boundaries. Many families with the same surname may have different gotras (clans) and traditional occupations. Genealogical research or community elders provide definitive lineage information.
