Surname # testers[1] Family clade info (incl. subclades) FTDNA Project[2]
Alden 3/2 R1b-FTC62332 Given the STR differences between the two Big Y testers, it is likely they descend from different son of John Alden. https://www.familytreedna.com/public/Alden?iframe=ycolorized[3]
Billington 2/2 R1b-FTA18300 Unknown if the two testers descend from different sons of Francis https://www.familytreedna.com/public/Billington?iframe=ycolorized[4]
Bradford 7/2 I-FGC72882 both presumably via son Maj. William.[5] Unknown if testers descend from more than 1 son of Maj. William https://www.familytreedna.com/public/bradford?iframe=ycolorized (Group 3)
Brewster 27/3 I-FT1754 1 from Love, 2[6] from Johnnathan>Benjamin>William FT1754>FT759 https://www.familytreedna.com/public/BREWSTER?iframe=ycolorized
Cooke 7/4 I-FGC57472 only son Jacob has living Y-DNA descendants. Three of the four Big Y-700 testers descend from Joseph7Cook (FGC57464). The fourth Big Y-700 tester has not been able to trace his lineage prior to the 19th Century, but almost certainly is a patrilineal descendant of Francis. https://www.familytreedna.com/public/cook/default.aspx?section=ycolorized (I2 Lineage 3a)
Doty 100/3 R-FT78842 1 subgroup Edward-Samuel-Benjamin 1-2-3 FT78230[7] https://www.familytreedna.com/public/Doughty-Doty?iframe=ycolorized (Group R1b...)
Eaton 8/2 R-FGC53179 Unknown if testers descend from different sons of Francis Eaton https://www.familytreedna.com/public/Eaton?iframe=ycolorized (4. R1b Haplogroup: Eaton Lineage III-FranPly)
Fuller 37/25[8] R-Y85916 see Fuller Big Y results https://www.familytreedna.com/public/Fuller-FamilyFinder?iframe=ycolorized (1 and 1a.)
Hopkins 8/2 R-FGC71615 Only son Giles has living Y-DNA descendants. Unknown if testers descend from different sons of Giles https://www.familytreedna.com/public/HopkinsDNA?iframe=ycolorized (Hap'group R1b (M343;M269 etc) - Genetic Family D)
Howland 9/2[9] R-A6708 Descendants of two different sons of John Howland tested. No subclade identified (yet). https://www.familytreedna.com/public/Howland?iframe=ycolorized (John Howland through son ...)
Rogers 8/8 R-FT59523 Surviving Y-DNA lines only from son Joseph. Descendants of 2 of his 3 sons tested. https://www.familytreedna.com/public/ThomasRogersoftheMayflower?iframe=ycolorized and https://www.familytreedna.com/public/rogers.sc.ga.al.tx.nm.ca?iframe=ycolorized (R1b-M269>P312>Z290>L21>DF13>Z253>FGC3268>ZZ6_1>BY43439>FGC59524>FGC59535>FT260099 (Isles-Keltic))
Samson 2/2 I-FTB4532[10] Testers known to descend from different sons of Henry Samson https://www.familytreedna.com/public/PilgrimHenrySamsonKindred?iframe=ycolorized
Soule 57/13[11] I-A20032 George2 20/2 A20032. John2 BY32573. Nathaniels ZW20.[12] https://www.familytreedna.com/public/GeorgeSoule/default.aspx?section=ycolorized
Standish 6/3[13] I-FT276480 Known to descend from at least two different sons: Alexander and Josiah. https://www.familytreedna.com/public/STANDISH/default.aspx?section=ycolorized (Group 01)
Warren 2/2 E-FTC19215 Both testers lineage: Cornelius6 Warren (Samuel5, Samuel4, Richard3, Nathaniel2, Richard1). The Warren surname DNA Project currently does not list anyone claiming Richard Warren as their Most Distant Known Patrilineal Ancestor (MDKPA)
White 3/1 R-FGC28001 https://www.familytreedna.com/public/white?iframe=ycolorized (subgroup R --- 1324.1410.11-13.000---William White Mayflower Passenger Haplotype)
Winslow 2/2[14],[15] I-FT334733 https://www.familytreedna.com/public/Winslow?iframe=ycolorized (top)
  1. Total Y-DNA testers/Big Y testers.
  2. Also see: https://www.familytreedna.com/public/mayflowersociety?iframe=ycolorized
  3. Currently no Y-DNA descendants in project.
  4. Currently no Y-DNA descendants in project.
  5. Only a very small number of Y-DNA descendants of Jonathan (son of Gov. William) are known. None known to have done any DNA testing.
  6. One of the lines presumed to be from William, but unable to fully document all lines of descent.
  7. https://discover.familytreedna.com/y-dna/R-FT78230/story documents 3 individuals falling under this subclade. Two fall under an additional subclade: FTB93672.
  8. Some individuals descend from non-Mayflower Fuller's. Specifically Robert Fuller of Salem & Rehoboth and Capt/Dr. Matthew Fuller of Barnstable.
  9. Descendants of John Howland (One descendant not STR tested, but Big Y-500 tested). There are also 4/3 descendants of John's brother Arthur and 9/2 descendants of John's brother Henry tested. Currently, descendants of Arthur fall under subclade FT62874 while descendants of Henry fall under FGC58211 (both of these individuals descend from Henry's son Zoeth).
  10. In addition, two descendants of Henry Samson's paternal first cousin, Abraham Sampson, have also Big Y tested and fall into a different subclade of FTB708>FTB635. Thus we are certain FTB4532 is limited to descendants of Henry Samson.
  11. This includes folks who tested at other DNA companies such as YSEQ, Dante Labs and Nebula Genomics.
  12. Three tested. Two descend from subclade: A20044.
  13. In addition, the Standish DNA Project also contains two individuals who claim to descend from a Standish family in England. They both took the Big Y-700 test and have been found to fall into parent clades (FT276288 and its parent clade FT277048) of the Myles Standish clade (FT276288>FT276480).
  14. One of the two testers does not have the Winslow surname, nor traces his patrilineal line back to the Winslow family, but his Big Y-700 clade result indicates he must descend from Gov. Edward Winslow.
  15. Descendants of Gov. Edward Winslow. In addition, there are 6/2 descendants of Kenelm Winslow (brother to Edward), 1/1 descendant of John (whose wife, Mary Chilton, was a Mayflower descendant) and 2/1 other Winslows whose ancestry is currently unknown. The descendants of Kenelm Winslow (unknown whether they descend from different sons of Kenelm) belong to subclade BY108126.
