About the origin of the name,”Sirmour” there are quite a few surmises. One view being that the state derived its name as Sirmour because of the senior position it held amongst the princely hill states. Another version is that at the earliest times the capital of the state was at Sirmour and the state was so called after the name of the capital. But,how the word Sirmour originated is not known. Third version being that the state was founded by Raja Rasaloo of Jaisalmer whose one of the ancestor’s name was Sirmour and who belonged to Rasaloo family. Beyond this, nothing definite is traceable.
