A second project of the same kind: the distribution of clan names across Punjab's villages.
The information exists in the electoral rolls, which are public, and in the village directories where a village is named for a got.
A map of where Sidhus, Gills, Sandhus, Randhawas, Cheemas and the rest actually live, village by village, would show the pattern of medieval and early modern settlement in a way no document does, because the clans moved as groups and settled as groups.
It would also show what happened in 1947, since the gots concentrated in the western districts are now represented in Indian Punjab only by refugee populations, and the reverse in Pakistan.
Comparing the got distribution of Indian and Pakistani Punjab would show which clans are shared across the religious divide, which is a fact people on both sides mostly do not know about themselves.
The data is public on both sides. Nobody has put the two together.
The information exists in fragments. The colonial settlement reports recorded got by village for revenue purposes, and the electoral rolls carry surnames village by village now.
Nobody has put the two together. A map of got distribution across Punjab, then and now, would show the settlement history of the plain and the movement of 1947 in one image.
The obstacle is that surname is not got in the modern record. Many people use Singh or Kaur and the got appears only in speech, so the roll cannot be read directly.
