Kindo has launched a Hindi interface to their popular genealogy service. Now, you can interact and build your family tree entirely in Hindi. Hindi is among the top 5 spoken languages in the world, with about 500 million native speakers of the language.
As per Nils Hammar, co-founder of Kindo:
“We believe Internet access and usage will grow among Hindi speakers over the next few years, and that many Indians will want to use the service in their mother tongue. Apart from connecting typical Indian homes, Kindo will provide great assistance to families of many Indians who are based all over the world.”
Here’s a screenshot showing Sachin Tendulkar’s family tree in Hindi:

While the UI and the service is top notch and the Hindi implementation is awesome, I am skeptical if such a service would be popular in India for two reasons:
1) Genealogy has never been very popular with Indians. True to Indian culture, Indians end up keeping close ties with family and even extended family. Due to such close knit families and stories from your grandma, its not too difficult to track down your anscestors. Unlike the US, where majority of the people can trace back their origins to an ancestor in Europe.
2) Current, low Internet usage - especially amongst the native Hindi speaking population.
As an aside, Ibibo also has a family tree service called OneFamily.
