In Jainism, “Gangerwal / Gangerawal” is a community-family gotra name, not something defined in Jain scriptures, so its exact “kingdom of origin” is not clearly fixed or agreed upon.

A few key points:

1. Jain āgamas and main śāstras do not list such gotras.

- Gotra names like Gangerwal belong to specific Jain Vaishya communities (often from Rajasthan and nearby regions). - They are social / genealogical labels, not religious categories set by Bhagwan or by Jain scriptures.

1. For Gangerwal in particular, historical records only show it as a gotra/lineage name, usually among merchant Jain communities that spread in parts of Rajasthan etc.

- Some older community directories show “Gangerwal” within certain Jain groups, but they do not clearly connect it to one definite ancient “kingdom” (like “it came from XYZ Rajya”).

1. Because of this, any very specific kingdom-claim (for example, “Gangerwal came from such‑and‑such king’s rajya”) is based on local oral tradition, not on universally accepted Jain historical sources.

So, from a Jain-dharma point of view, we can only say:

• Gangerwal is a Jain community lineage name (gotra) arising from certain merchant Jains, most likely in/around Rajasthan‑region society,
• but no authentic, commonly accepted Jain textual source clearly ties it to one particular kingdom by name.

For an exact family answer, you would need to check:

• old lagna‑patrikā / family records,
• your samaj’s history book or community register,
• or elders in your own Gangerwal Jain community, who may preserve a specific oral story of origin.
