A tabulation of basic biographical and geographical details of persons who have been Prime Ministers of India, including the Acting ones. This may answer any doubts you may have had from the previous post.
Note that V.P. Singh was known as the Raja of Manda, though this was a zamindari estate and not a princely state.
Also to confirm that even some official websites have confusing information, even if they are produced by the Lok Sabha themselves. Gulzarilal Nanda was MP from Sabarkantha (Gujarat) when he was Acting PM and was later MP from Kaithal (Haryana). He also lived for a slightly longer time than Morarji Desai, but still missed crossing a century.
