I have written on Brahmin Gotras and I indicated that compiling the list  was difficult as Brahmins  have scattered and been living in different regions.

Brahmin Gotra List

Those ho have migrated have adopted the language of their region as their mother tongue and adapted themselves to the region to which they have migrated.

And over a period of years Brahmins have started using their professions as their surnames ,as against the Hindu practice of using Sharma as their surname and for indentification their Pravara/Abhivadan Mantra.

So when one has a surname like Upadhyaya it merely denotes the profession and not a caste.

To find it one has to check the Pravara.

These factors made it difficult for me to update on Brahmin Gotras.

One point to remember is that the primary Rishi of a Gotra is the founder of the Clan while  the Pravara lists the famous Rishis of the lineage.

The Gotra may have two origins for classification.

Putra Parampara, lineage through  sons and

through Disciples, Guru Sishya Parampara.

The number of Rishis mentioned in Abhivadna Mantra may be from one to 19.

And there are sub-sects.

This is due to a Rishi with more than one wife.

Please check my article on this Pravara  Why  three  five Rishis

Eka Rishi Gotra is  rare to come by.

There are two in this category.

They are,

Vasishta Vaasishta – Ekarsheya

Haritha Vaasishta – Ekarsheya

Agasthya Agasthya – Ekarisheya, pravaranvitha:( sub lineage Rishis)
Idhmavaaha Agasthya – Ekarisheya, Pravaranvitha:( sub lineage Rishis)

My surmise is that this Eka rishaya Gotra belongs to classification based on Guru Sishya Parampara and as such Eka Rishi is mentioned.

Details of the progeny of Agastya and Vasishta are not found in detail and also their contribution to Sanatana dharma.

Clarification welcome.

Some Gotras which might have been left in My Gotra List.

Likely that there are repetitions.
