Thanks for calling attention and for the article. I've detached Daniel Doane's wife as a daughter of Nicholas Snow & Constance Hopkins & added the article as document as a citation.
To summarize:
"Does anyone know if GSMD [General Society of Mayflower Descendants} has budged re Constance (Snow) Doane?" < [https://www.wikitree.com/g2g/1673435/does-anyone-know-if-gsmd-has-b... Wikitree discussion] > "A couple of years ago, the GSMD tracked down matrilineal (all female line) descendants of Daniel Doane and his wife (said to be Constance Hopkins). They found and mtDNA tested two individuals. Neither one of them matched the known mtDNA signature of Constance (Hopkins) Snow, discovered by mtDNA testing matrilineal descendants of her other known daughters. Interestingly, the two individuals supposedly descended from Daniel Doane fell into different mtDNA haplogroups. Either one (or both) individuals' lines were wrong, or Daniel Doane was married more than once. In the end, this mtDNA testing likely puts the "final nail in the coffin" for Daniel to have married a daughter of Constance (Hopkins) Snow." (answered Dec 13, 2023)
My caveat would be that there does not yet seem to be a published study showing the full parameters, so we can evaluate the data for ourselves more transparently.
As of a year ago:
"I am a Mayflower Society State Historian, and according to the latest info I have from GSMD, this rejected connection (rejected in 1948) is still in place. The rejection statement is that Daniel Doane is not proven to be married to Constance, d/o Constance Hopkins and Nicholas Snow."
