Answer

“Dakalia” is not a spelling I could verify in the Oswal gotra lists I found. The closest Oswal names in the lists are Takalia and Dhakadia. In one Oswal gotra listing, Takalia appears as a sub-gotra under Bafna, and Dhakadia appears as a sub-gotra under Shrishrimal. ( jainsamaj.org)

Explanation

In Oswal tradition, gotra spellings can vary by region, family usage, and transliteration. So “Dakalia” may be a local pronunciation or alternate spelling of one of these two names, but I cannot confirm that as a standard written gotra name from the sources I checked. ( jainsamaj.org)

Takeaway

If you are matching family lineage, the safest approach is to check the exact spelling in an old family record, temple register, or community document. ( jainsamaj.org)
