Answer

If you mean the Oswal Jain gotra, Daga is a Jain family-lineage name, and the traditional Oswal sources list Malu as one of its sub-gotras. Those sources also say Daga has 52 sub-gotras. ( oswals.net)

Explanation

The Daga gotra has more than one traditional origin story in community memory. One account links it to Doongar Singh, a Chauhan who took shelter of Acharya Jain Kushal Suri, accepted Jainism, and his family became known as Daga. Another account connects Daga with a Rathi/Maheshwari family of Ratanpur; in that line, the Malu branch is said to have emerged. In Jain social organization, gotras work as family-lineage groups within the wider Jain community. ( oswals.net)

Spiritual Understanding

In Jain tradition, a gotra is a social and family identity, not a measure of spiritual superiority. In Jain Dharma, true worth comes from right faith, right knowledge, and right conduct, not from lineage name. So Daga should be understood as a community lineage within Jain society. ( jainqq.org)

Takeaway

In short: Daga is an Oswal Jain gotra with traditional origin stories, and Malu is one of its sub-gotras. The same tradition also associates the gotra with Shri Ashapura Devi / Shakambari as kuldevi in some accounts. ( oswals.net)
