Is tiwari a gotra or shaashan of bhardwaj gotra?

In Hindu culture, a gotra refers to a lineage or clan within which one's ancestors are traced. Tiwari is a gotra, while Bhardwaj is another separate gotra. Gotras are important in determining familial relationships and marriage eligibility within Hindu communities. Shaashan, on the other hand, typically refers to governance or rule and is not directly related to the concept of gotras.
