What is the purpose of the DNA Project?

The original goal of the project was to see if DNA testing can discover a link between the early Sheldon Ancestors or Progenitors. Particularly useful is the testing of men named Sheldon. Combined with traditional genealogical research the results can be compared to other Sheldon men. Using genetics and the markers on the Y chromosome, similar patterns may become clear. We urge Sheldon men to submit a test sample to Family Tree DNA for the 37 marker test – click FTDNA for a link to their website and more information.  One can also contact the DNA Committee Chair for information regarding pricing on smaller tests in order to prove connection to a particular line. Learn about our ongoing project and other topics related to Sheldon DNA. . .

The current project objectives:

  1. Assist members in proving their relationship to one or more of
    the original 5 Colonial Sheldon lines.
  2. Determine the English ancestry of the original 5 Colonial Sheldon’s.
  3. Encourage greater participation in the SFA DNA project by our
    members and our English cousins. 


 Progress so far…

The Sheldon Family Results from testing at FTDNA:

Group A: John (8) of Pawtuxet and Providence RI, Richard (22) and Godfrey (4) of Maine and MA and an English tester with ties back to Bakewell, Derbyshire, England Haplogroup E117>M35>V22    We are currently researching the connection to the recorded SHELDON tree going back in Derbyshire.

Group BJohn (13) of Kingston, RI and Isaac SHELDON (5) of Windsor CT Haplogroup R1b>U106>Z156> DF96>S11515>S15663>FGC62079   We cannot rule out that this is a separate Derbyshire line or that its origins lie elsewhere in England.

Group C: Not related to group B, unknown ancestors

Group D: Haplogroup J: M172>L26>PF413 Argyllshire? Scotland? Maybe related to Montgomery. Represents two English testers with recent ancestry from Staffordshire.

Our testing efforts are focused on recruiting and testing more SHELDONS in England.


There are 3 major types of DNA for genealogical use. The easiest to use is YDNA, followed by autosomal (atDNA) and finally mitrochondrial DNA (mtDNA).

YDNA is the Y chromosome that all men inherit from their fathers virtually intact. The Y chromosome contains YSTRS (Y Single Tandem Repeats) and SNPS (Single Nucletide Polymorphisms). Women do not have a Y!

XX = female

XY = male.

Only men with the surname SHELDON are able to do the YDNA test for SHELDON purposes. We do however have many non-surnamed SHELDON descendants in our project!

ALL men and women with SHELDON heritage can test their atDNA and matches to other SHELDONS will be found within 4th-5th cousins and sometimes as distant as tenth cousins. This can be useful to those trying to determine their relationship or who are unsure of where there SHELDONS originated.  Or those just trying to prove they are who they think they are.

ALL men and women can test their mtDNA however this is of limited use for SHELDON genealogy purposes but may be helpful to those with specific research interests on their mtDNA line.  (This is always inherited through the mother and is the mother’s mother’s mother’s etc line).

DNA testing for genealogy is accomplished through either spitting into a tube or through swabbing the inside of the cheek depending on the company’s protocol.  Testing is relatively easy but everyone doing a DNA test must be prepared for unexpected results.  They happen infrequently but they do happen.  DNA only reports the truth and has no agenda.
