There are now many types of DNA tests available. To participate in this study, make sure the test is a Y-DNA test!

Y-DNA results sorted by haplogroup, and family within haplogroup. Y-DNA profiles for families with at least 3 tested individuals are on their own page; Families with just 1 or 2 tested individuals have been grouped into a miscellaneous page at the bottom their haplogroup.

Thus far, all P-rr-tts tested have fallen within one of four different haplogroups (main branches of the human family tree). These particular 4 are called E-M35 (previously E1b1b1), I-M253 (previously I1a), I-P37 (previously I2a) & R-M269 (previously R1b1a2 and its subbranches).

The Y-DNA results indicate that most of the P-rr-tt families tested are not related to each other-- thus, the Parrott and related last names have come into use on several independent occassions, which is consistent with the premise that Parrott comes from the French for Perot, meaning little Peter, essentially, Peterson. Other P-rr-tt families may represent a toponym, indicating an origin near the the River Parrett in Somerset. Those P-rr-tt families that migrated to the American Colonies before ~1710 have grown to enormous size, and account for most of the individuals bearing this name in the USA.
