False, N1c1, R1a and I2a are all Slavic Eastern European haplogroups, Varangians were Baltic Slavs from South Baltic coast, further N1c1 in Scandinavia is practically non existent and was brought with Eastern European migration from South Baltic coast probably during Teutonic crusades in the region, the N1c1 was assigned a Scandinavian origin through false pretenses because some people that were Swedish today were found to have haplogroups close to his N1c1 however there were also a number of Eastern Europeans from Russia, Ukraine, Estonia etc... that were also found to contain similar haplogroup so his Swedish origin is not accurate, further N1c1 in Sweden is small and insignificant and comes from two sources Finnish N1c1 and South Batic Slavic N1c1 and this branch grew more heavily after Ruric came to Russia and ruled, the region with highest N1c1 in Sweden is around Birka but in the early medeival era this was a South Balto-Slavic trading post set up by foreign migrants from this region so this explains also the N1c1 presence.Rurik was a Varangian prince. The Varangians were of Viking stock from Scandinavia (I2a2) who ruled over the Finnic (N1c1) and Slavic (R1a) tribes. Rurik's Finnic (N1c1) ancestry can be explained by the fact that he was a Kven Viking. 68% of Rurik's descendants had hg N1c1, while some Rurikid princes carried I2a and R1a. For instance, Prince Stanislaw Antoni Czetwertynski was found to belong to the I2a2 haplogroup, which is typical for the native population of the Belarussian-Ukrainian Polissiya region. According to the Y-DNA haplogroup chart compiled by the Rurikid DNA Dynasty Project, some R1a Rurikid princes were descendants of Rurik on maternal branches (i.e. the Dunin clan), which is why they didn't inherit N1c1 through the paternal line.
