There isn’t a canonical, universally accepted list of Jain gotras, including Bavalecha. Different Jain communities and regions maintain their own family/gotra names, and Bavalecha may appear as a variant or local name in some records (often related to the broader Valecha/Veval family groups in community directories). If you have a specific community or region in mind, I can explain that practice more precisely. You can read more about the nature of gotras in Jainism here
