Partial results are now available on subject kit and a "19" is present, as expected on 520. I suppose that we should wait for kit 63451 upgrade to 25 results to consider the ramifications of the "15" on 464c on 63451's brother, kit 31268. However, this John R. Queen of 1853 is a son of my Alfred of 1810. The 19's are falling into place like cordwood on a pile. Gene
