I used Felix Immanuel's "Ancient Calculator":
Ancient Calculator
Ancient Calculator will tell you how much percentage of DNA and/or compound segments is shared between an ancient DNA and the autosomal file. In other words, it tells your total percentage of shared ancestors in each others pedigree. The tool includes 59 ancient DNA which allows to compare any autosomal file with ease. It supports FTDNA, 23andMe and Ancestry files.
Here are my results for Copper-Bronze Age and younger samples (I added cultures):
Bronze Age BR2 comes first again (1/5 - 1/4 of shared ancestry):
BR2 - 22,36% - Kyjatice, Hungary

*It is not certain whether RISE98 was one of Battle Axe people. According to Artmar:
Artmar said:
RISE98 wasn't buried in Battle-Axe rite - only on burial site used previously by Battle-Axe people.
**Is it Stuttgart, another LBK, or some composite created from several LBK samples?
