Gill is one of the largest Jat gots and is distributed across the Malwa, the Doaba and the Majha, with a particular concentration around Ludhiana and Moga.
The tradition derives the name from a founder of Rajput descent, with the usual medieval migration.
Gill villages, and villages named Gill, Gillan, Gill Kalan and so on, are found in most Punjab districts. The village of Gill near Ludhiana has been absorbed into the city.
Like the other large gots it is heavily represented in the army, in emigration, and in Punjabi public life.
The rule against marrying within one's got means a Gill from Ludhiana and a Gill from Ferozepur, with no traceable common ancestor, still cannot marry, which is a strong indication of how the rule actually functions: it is about the name rather than about descent.
Gill villages appear across Ludhiana, Moga, Ferozepur and Faridkot, and Gill is also a locality of Ludhiana city, a village absorbed as the city grew.
The got carries no ritual rank of its own. Among Jats the gots are formally equal and the differences between them are of place and of landholding rather than of status.
In Britain and Canada, Gill is common enough to function as an ordinary surname, and its origin is invisible to people outside the community in a way it never is inside it.
