Gautam is a Nepali last name found among Brahmin and Tarai-Hindu communities. Some families connect this name with Atreya (Purbiya) or Rajput lineages. Spellings and traditions may vary by place and family.
Research summary
What the Gautam record currently shows
HamroBansa records Gautam as a Nepali last name. The links below bring together reviewed community classifications, gotra traditions, place associations and public family histories without treating a shared surname as proof that two people are related.
The 2017 Krämer table records Gautam in two rows. Its Bahun row includes Atreya in the clan/gotra column and Purbiya in the Brahman group column. A separate row records Gautam under Tarai-Hindu with Rajput as the accompanying classification. Those details belong to different rows of the source; Atreya should not be applied to the Tarai-Hindu row by association.
Reading this as a family-history lead
This table documents that the spelling Gautam occurs in more than one classification. It does not say how many Gautam families follow either tradition, where a particular family lived, or whether two Gautam households share an ancestor. A branch-specific gotra claim needs its own family evidence; the catalog row alone is not that evidence.
Related last-name records to explore
These links share a reviewed gotra connection or a recorded community classification with Gautam. They are research leads, not evidence that families are related.
A shared last name does not establish a relationship between families. Compare names, dates, places and original records before drawing conclusions. Our editorial standards explain how catalog links and citations are assessed.
