Description:
Umrigar is a surname mostly used by Parsis in India. Its tied to a group within the Parsi community, but Parsi society wasnt organized into strict sub-groups like some other Indian communities. Family history and where their ancestors lived mattered, but formal sub-castes werent clearly defined.
We can guess at a few possibilities, though. Adding an extra "a" might give you Umrigaar (a common mistake in copying). Changing the last letter slightly could lead to Umriger, maybe due to how people spoke the name in a certain area. A shorter version, Umri, is also possible, but that depends on family traditions.
