History:

I like how you emphasized the mystery of its origins—it makes this name feel even more unique.

This names location is key to figuring out what languages are linked to it. If this name is big in India, then Hindi, Gujarati, Marathi, Telugu, Tamil, Kannada, Malayalam, Bengali, and Punjabi could be connected. If its popular in a specific Indian area, the local language(s) are more likely. If this name is popular elsewhere, the languages spoken there would matter. For example, Spanish would be likely if its common in a Spanish-speaking country.

Description:

Its Sanskrit roots mean "message" or "news," so names like Sanjeevani ("life-giving message") are linked. Slight spelling changes like Sandeshh or Sandeesh might also show up due to different ways of writing the name. So, variations arent just direct changes, but also names with similar meanings or sounds.
