I was tracing the Y line back from Harris-1701 and I noticed that there is a test-taker listed as a probable Y-chromosome carrier for this profile and for several profiles going backward in the line. But then at Harris-14046 there is a different test-taker listed, and it's this test taker that is listed for the rest of the line. How does WikiTree pick a test-taker to mention on a profile? Shouldn't the test-taker listed for Harris-1701 be listed all the way through? Can it only show one at a time?
