Sandhu is among the largest Jat gots and is found across both Punjabs, in the Majha, the Doaba and in what is now Pakistan.
The Attariwala family, which produced Sham Singh Attariwala Ji who died at Sobraon in 1846 and Chattar Singh and Sher Singh who led the Second Anglo-Sikh War, were Sandhus of Attari.
The tradition places the got's origin in Rajput descent and a medieval migration, on the same pattern as the others.
Sandhu villages are distributed widely and the got is one of those found in strength on both sides of the 1947 line, which means Sandhu families in Indian Punjab and Sandhu families in Pakistani Punjab share a clan name and nothing else now.
In the diaspora it is among the commonest Punjabi surnames in Britain and Canada.
The Attariwala family took its name from Attari, the village on the border, which the family founded. Its estates there ran into the twentieth century.
Sandhu is found among Sikhs, Muslims and Hindus, which is true of most of the large Jat gots and is a reminder that the got is older than the religious divisions later laid over it.
Villages carrying the name are scattered across the Majha and the Doaba and into the districts now in Pakistan. As with the other gots, the pattern of those names is a record of settlement that nobody has mapped.
