There is an old grave site in Southern Osthrobotnia, Finland called Leväluhta. THe skulls have been studied by Marja Formisto and they are similar to the skull remains of Eastern Corded ware culture or the Fatyanovo culture.

Some info about them I found from the Internet:
We have knowledge of the racial characteristics of the ancient Kyro people because of the discovery of about 100 skeletons that were found in the Levähuhta springs in Storkyro and in Keldomäki in Vörå. How the dead ended up in the springs is unclear, but archaeologists think it probably was a normal burial site.
The skeletons of the ancient Kyro people were small young people, thought to be Lapps. Their skulls were long and narrow, which is a deviation from the form of the Lapps’ heads and their physical structure separates them from the larger build of the Finns and Scandinavians.
One who later researched the skeletons of the ancient Kyro people is Tarja Formisto who received a Doctor’s degree at the University of Stockholm in 1993. She completed her research that compares her own results with information of different people who lived within a radius of 100 kilometers. The results showed that the ancient Kyro people greatly resembled the people who lived in central Russia, around the area of the rivers Volga and Oka. They were of the Fatjanovo culture from the Bronze Age.
