Undesigned Coincidences in Secular History: Where's Paoli?

Today, one more co-incidence between Whittaker Chambers's testimony and that of Alger Hiss--where did Hiss's wife grow up? Chambers says "near Paoli," Hiss says "Frazer." Both are true, and the similarity with natural variation provides evidence for Chambers's close acquaintances with the Hisses. I compare this to the evidence of undesigned coincidences that the author of Acts really knew the Apostle Paul.
