This project is desk research. Nobody working on it has stood in most of the places described. Pages marked as compiled from published histories have not been checked against a primary document, and they say so on the page.
The likely errors are of four kinds. Dates that the sources give differently and this site has picked one of. Attributions of buildings, events and quotations that rest on tradition rather than on evidence. Names and spellings transliterated from Gurmukhi or Shahmukhi in a form a local person would not recognise. And the general error of writing about a place from a distance and getting the emphasis wrong even where the facts are right.
The fourth is the most likely and the hardest to see from here.
The correction that matters most is from someone who lives in the place or whose family did. That takes precedence over any published source cited on the page, and it should be sent with whatever it can be supported by: a photograph of an inscription, a name, a date, a document, or simply what you were told and by whom.
A page that is corrected is doing its job. A page that stands uncorrected for years because nobody local has read it is not.
A page here can be wrong in four ways: the fact is wrong, the source is wrong, the emphasis is wrong, or the page is about a place and was written by somebody who has not been there.
The fourth is true of nearly every page and it is stated. It is the one that only a person in the place can fix.
A correction is most useful with the page name, the sentence, what is actually the case, and how you know. All four, and the page changes.
