In Jain tradition, “kuldevta / kuldevi” is not fixed by scripture; it is decided by each kul (family–line), often based on old family vows and local tradition.

For the specific surname / family group “Aunchaliya,” there is no standard, universally–known kuldevta recorded in Jain texts that I can reliably quote. It can also differ even between branches of the same surname (for example, some worship a particular Jain Tirthankar, some a Jain Yaksha/Yakshini, some a specific temple–pratima connected with their ancestors).

Because of this, the only honest and dharmic answer is:

• There is no single, scripturally fixed “Kuldevta of Aunchaliya” that I can state with certainty.
• You should check:

- Old family pattas, vows or chadavas (donation records) if preserved. - Ask elders in your extended family or your traditional family pandit / granthi (if your family keeps one). - The main Jain temple where your ancestors used to visit or where family ceremonies (like jinalay–pravesh, lagna, etc.) were usually done; sometimes the kuldevta is recorded or well known there.

Until you confirm from these reliable family sources, do regular Jain worship that is always appropriate for all Jains, such as:

• Namokar Mantra
• Pooja / vandana of your Pancha–Parmeshthi and your own ghar–derasar’s main Tirthankar

This keeps your sadhana correct and within pure Jain dharma while you clarify the family tradition.
