How the Pope shall choose which one of the insultee's 524,288 candidate ancestors, that's not clear. You make a lot of assumptions about some people's family trees. What if the 17th grandmother is also your 16th grandmother on the other side? Eg, small village, grandmother has 6 daughters, they have 6 daughters, out of the 36 daughters 20 could be lineage grandmothers. In fact, the further back you go, the greater chance of overlap. (Note: growing up in a small town has no bearing on me thinking of this! None!)
