In Jainism, the concept of "gotra" (lineage) is not a standard or defining feature like it is in some Hindu traditions. A kuldevi (family deity) such as Padmavati may be an important family or clan worship for many Jains, but it does not determine or assign a Jain gotra per se.

What this means:

• If Padmavati is your kuldevi, that identifies your family deity or ancestral worship target, not a formal Jain gotra.
• Your practical lineage markers (if any) would typically come from your family records or the guidance of your temple/community, not from Jain scriptures.

If you want, I can help you look for a Jain-dharma resource that discusses kuldevi practice in Jain communities or how lineage and family deities are viewed in Jain tradition.
