This working layer records recurring surname and geographic signals without requiring them to resolve into a genealogy. Historic intersections are shown only to explain why a signal became notable.
A surname signal is a data point. A documented historic marriage is a separate data point. Their coexistence is recorded here without converting the resemblance into a claimed ancestral relationship.
Michaux & variants
Discovery pathway
An Ancestry DNA contact from a descendant of Judith led backward through that tester's documented ancestry. The Quinn intersection was discovered during that reconstruction; it was not the premise used to find the DNA match.
Historic intersection
Susanne/Susannah Michaux appears in the reconstructed Michaux family and married John Quin/Quinn. Continuing backward places Suzanne Rochet immediately behind the Michaux line.
Search forms
Michaux and documented or plausible record variants are retained under their original spellings. Rochet is likewise retained with variants such as Rochette and de la Roche rather than flattened into a single spelling.
The Little Nightcap
The Michaux material also preserves the family tradition remembered as “the Little Nightcap.” On this site it remains family memory: distinct from the DNA signal and distinct from the documentary record, but part of the history carried by the descendants whose line brought this material into the research.
Riordan / O'Riordan
Historic name already known
Judith O'Riordan was already familiar from early research into the historic lineage associated with the Earls of Dunraven: Donogh Óg O'Quin married Judith O'Riordan.
Later autosomal observation
RIORDAN: 4 matches, 8–45 cM. Strongest result: 45 cM across 4 segments; 52 cM unweighted; longest segment 21 cM. The working notes mark the signal as matching QUINN.
The significance here is the recurrence of a surname already present in the independently researched peerage-era material. The recurrence is preserved as a phenomenon, not a declaration of descent.
Associated surname phenomena
Nash
21 matches, 8–43 cM; strongest recorded result 43 cM across 2 segments, 47 cM unweighted, longest segment 42 cM. Nash occurs immediately before O'Riordan in the historic Quin sequence studied.
Ashworth
Six Ashworth matches were recorded in the working material, ranging from 9–13 cM. Ashworth was among the names treated as an initially unfamiliar signal rather than a known Quinn-family surname.
Vernon
The working material records a Vernon autosomal signal above 34 cM. Vernon also occurs in the Virginia Quinn material and therefore remains a geographic/surname phenomenon to be plotted without presuming a pedigree from the signal.
Gould / Gold / Goold
The existing Carteret and Limerick pages preserve the separate Gould/Goold evidence streams. The autosomal work adds a Gold-and-variants observation of 55 matches, strongest 34 cM across 3 segments, 51 cM unweighted, longest segment 26 cM.
How these phenomena entered the research
DNA first
Michaux: a living Ancestry DNA contact led backward into the historical record and exposed the Quinn intersection.
Records first
O'Riordan and the Dunraven-associated names: the peerage-era lineage had been researched early. Later autosomal work caused familiar names from those records to reappear as measurable signals.
