Tindra (TIHN-druh) is a Swedish word-name meaning "twinkle, sparkle." This Scandinavian gem has only started being used recently, and I believe the earliest documented use of Tindra as a given name was in the early 1980's. Going by Sweden's name statistics, Tindra was given to 238 girls in 2011 and 307 in 2010. It's rank in Sweden in 2011 was #60, and in 2010 it was #51. When I did a search on the website it told me there are 5,713 people in Sweden named Tindra, and 4,022 of them had Tindra as a nickname (middle name?).
Over here in the U.S. Tindra is unheard of, with no children given the name in 2011 or 2010. The similarity to the new dating app Tinder might knock out any chance it had of being imported.
Just for fun, and since I already did Norway, here's Sweden's top 10. Go here for the full chart.
