Thanet line charts

These combination DNA/genealogical charts show test participants' results superimposed over traditional genealogical charts. The charts are abbreviated for simplicity, with numbers of generations being shown where names are omitted. Letter sequences under each name are abbreviated DNA signatures, showing only those markers that differ. The full DNA signature of each individual is available via a pop-up detail panel—the "+" sign. Ancestors' DNA signatures are derived from the test results of their partipating descendants.

Thanet chart 1 shows the ancestral lines of participants whose results match closely and whose genealogical paper trails identify them as descendants of Thomas Sackett the elder of Thanet, Kent.

The remaining charts show the ancestral lines of other partipants whose DNA matches the Thanet line but whose paper trails have not yet been fully established.

One participant, Robert E Sacket, who has DNA test results matching those of the Thanet line, is a descendant of Skene Douglas Sackett.

Weygant, in The Sacketts of America, recorded Skene's father as a Josiah Crego Sackett, a son of Captain Richard Sackett (c1678–1746), a descendant of the John Sackett of New Haven line. It has been established that Josiah Crego was not himself a Sackett, but was a stepson of Captain Richard. Skene may have been a grandson of Captain Richard, but neither this nor any other possible ancestry for him has been established.

This DNA test result identifies Robert and his ancestor, Skene Douglas, with the Thanet line. Given the lack of a paper trail, this could mean either (1) that Skene descends from Sacketts in the line of Simon the colonist or (2) that, if Weygant was right about his descent from John of New Haven, a link has been made between the lines of Simon the colonist and John of New Haven.

The ancestral line of Brian H Sackett, whose test results match those of the Thanet line, may be traced back to Aaron Sackett. Aaron's parents have not been identified.

Weygant recorded Aaron as a grandson of Captain Richard Sackett, but supporting evidence has not been found, and several other theories about Aaron's ancestry have been propounded. It is nevertheless interesting that DNA testing has resulted in a match between descendants of Skene and Aaron, both dubiously stated by Weygant to have been grandsons of Captain Richard.

The conclusion from this DNA test is similar to that for Skene Douglas: that Aaron either (1) descends from Sacketts in the line of Simon the colonist or (2) that, if Weygant was right about his descent from John of New Haven, a link has been made between the lines of Simon the colonist and John of New Haven.

The ancestral line of David Sackett, whose test results match those of the Thanet line, may be traced back with reasonable confidence to Captain Richard Sackett of Dutchess County, New York (chart 4.1). However, beyond that, his ancestry is uncertain.

Weygant, in The Sacketts of America, recorded Richard as a son of Jonathan Sackett and a grandson of John Sackett of New Haven (chart 4.2). Jacobus, in The Families of Ancient New Haven, written several years after Weygant's work but based upon original records, does not list Richard among the children of Jonathan. There are also arguments connected with the respective ages of Jonathan and Richard that suggest a link would have been unlikely.

It may be concluded from this DNA test that Captain Richard Sackett was of the Thanet line. If Weygant was right about Richard's descent from John of New Haven, then he too would be of the Thanet line and the link between Simon the colonist and John of New Haven would have been established. However, the probability that Richard's father was not Jonathan makes this an unsafe conclusion.
