There is limited evidence that Rubel and the Buekhart lines are related. All we have is that they're of European descent and have similar coloring.

From the diaries we know that the Grimm genetic attribute exists in family lines of different ethnicities (European and Japanese at least). If there were 7 Templar Grimms and not all were of the same family line, that implies multiple genetic lines contain the Grimm attribute in just Europe. Assuming there were Grimms with a less than monogamous morality and who travelled extensively, they may have "seeded" different people groups across multiple continents with the Grimm attribute. Assuming the offspring of such spreading of the genes didn't get put down as insane or possessed, there may be Grimm genes percolating through out the globe.
