From historic perspective the Frankfurt region is an interesting area. Jews were present in serious numbers in this region in 1096, that the historic knowledge on the Rhineland massacres is well kept.
The ftdna project site has 62 Y-DNA datasets. In total they are from 25 of the Y-DNA branches: 5 of E1b, 2 of G, 5 of J1, 4 of J2a, 1 of J2b, 1 of Q, 1 of R1a, 5 of R1b, 1 of T. None of these suggests an origin in Germany. The oldest reported genealogical data is for R1b-L584 in 1285 (Rome), E1b-V22 in 1390 in Prague, J2a-L210 in 1390, resp. 1575, J2a-L556 in 1285 resp. 1395, R1a-M582 in 1430 in Nurnberg, Q1-Y2200 in 1430, G-M377 in 1440, G-PF3316 in 1455 in Porto.
5 out of 62 had Y-DNA that was not related to other Jewish Y-DNA ("none" in the pie diagram). All five of them were R1b. Three of them were measured with 67 markers; two of them had only 37 markers, and are not used here, because of the limited statistics.
The three ancestors of these three persons became probably Jewish in Europe; see below.
The modals of the people that were not measured in the known branches are reported in Frankfurt modals page.
