Using the Dodecad K12b data provided by Jovialis's Ancient Rome Test v1.0, I ran each Medieval sample separately against modern populations. As Angela pointed out, many of the skeletons from the Latium region that were tested may have been pilgrims from other parts of Italy or Europe. This should provide better insight for the personal matches of anyone who uses the genetic distance calculator. I have listed the samples by burial location.

Palazzo della Cancelleria, central Rome (771-1411 calCE)

Those samples are very heterogeneous in origin and none seem to be local. R1219 looks Austrian, R1220 may come from Southeast France or the Alps, R1221 and R1224 from Aosta Valley, R1283 from the Marche, R1285 and R1287 from Corsica, Tuscany or Romagna, R1285 and R1286 from Germany, R1288 might be from modern Belgium, and R1289 from northern Spain.

Villa Magna (820-1430 CE) in Anagni (Frosinone)

In contrast to the Cancelleria, most samples here appear to be local or South Italian. The exceptions are R55 and R61 (both North Italian), R62 (French/Belgian), and R63 (Spanish).
