I have heard the name. But I don't know its location. If you are lucky, you may google it and find it. I also suggest that whenever you visit Tirumala, please first visit the varahaswamy temple. My father followed it as a practice for as long as I can remember. Varahaswamy offered land to Lord Venkateshwara and supported him during his marriage. I would like to know more about Varahaswamy. Hope Tamilbrahmins.com can share an article on the same.
