About us
As of Jan 2021 we have seven patrilineal (direct male line) descendants of the Howland family of Fen Stanton who have taken a Big Y test. Three are descendants of Arthur Howland, two are descendants of Henry Howland and two are descendants of Pilfrim John Howland. These results document where the family haplogroup falls under R1b-A9703. For more information, see https://mayflowerdna.org/wiki/index.php/Howland_(Y-DNA)#DNA Results A9703
Additionally, the three descendants of Arthur Howland all fall under Haplogroup FT62784 while the two descendants of Henry Howland both fall under FGC58211. The two descendants of Pilgrim John Howland fail to document a mutation unique to his descendants.
Within the 111 STR results, the four descendants of Arthur Howland all have DYS464a=16 (while the descendants of Pilgrim John and Henry have DYS464a=15). In addition, three of the four Arthur descendants have DYS576=18 (while the descendants of John & Henry as well as the fourth Arthur Howland descendant has DYS576=17). Both of these mutations show up within the first 37 STR markers (and everyone in the project has tested at least 37 STRs). Given the fact there are two separate STR mutations, it is likely that male Howland descendants who have both DYS464a=16 and DYS576=18 are descendants of Arthur while males who have only one of these mutations might be a descendant of Arthur.
Fewer individuals have extended their STR marker testing to 111 markers. We currently have three descendants of Arthur, four descendants of Pilgrim John and four descendants of Henry who have tested 111 STRs. The four descendants of Henry all have DYS485=14 (with all others being DYS485=15) All four also have DYS505=11 (with all others being DYS505=12). Once again, because we have two separate STR mutations, it is likely that male Howland descendants who have both mutations are descendants of Henry while males who only have one of these mutations might be a descendant of Henry.
There are no STR mutations (within the 111 STRs) found to be in common with Y-DNA descendants of Pilgrim John Howland, but in general, results which do not have any of the above STR mutations are likely to be descendants of Pilgrim John.
We also have two mtDNA results from two "umbilical" descendants of Elizabeth Tilley through two different daughters (Desire & Lydia). These results document where Elizabeth fell under the H1a1 mtDNA Haplogroup.
