Tamil community format
Iyengar Marriage Biodata Format
Iyengar biodatas belong to the Tamil Brahmin (Vaishnavite) community and follow a very similar structure to Iyer biodatas — Gothram, Natchathiram and a detailed horoscope section are standard — with a couple of Vaishnavite-specific additions: some families note their Sampradaya (Vadakalai or Thenkalai) and their family's Acharya lineage or Mutt affiliation, since these can matter for religious practice compatibility.
Fields commonly used
Gothram, Natchathiram, Sampradaya (Vadakalai/Thenkalai) where relevant, and horoscope details.
Frequently asked questions
Should I mention Vadakalai or Thenkalai in my biodata?
It's optional but commonly included, since some families prefer to match within the same Sampradaya — stating it upfront avoids back-and-forth later.
Is the biodata format otherwise different from an Iyer biodata?
Not structurally — personal, education, family and horoscope sections are the same; the differences are mainly in a few Vaishnavite-specific terms.
