I have today detached the parents of Francis Brown of New Haven, based on the first paragraph of the Overview.
Robert Charles Anderson (The Great Migration Begins, three volumes) is the most up-to-date source for the families and lineage of this important period in American history (1620-1640). If he does not find reliable, primary sources or a persuasive argument for the parents of Francis Brown, then the Geni tree should reflect this.
However, when we detach parents, it's a good practice to have a public discussion, in case someone have additional information.
Here's an excerpt of a message that managers of the profile received that prompted my reviewing the profile:
Message
"I notice that the profiles linking Francis Brown back to descendency from Sir George Browne, Sr. (who died in 1483) and Elizabeth Patton aren't official Master Profiles."
"It does look from some cursory research that George Browne had another son George Brown (https://en.wikipedia.org/wiki/George_Browne_(died_1483) who had a Simon Browne (https://www.wikitree.com/wiki/Browne-1953) who had a Thomas Brown (https://wc.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=andwai&am......), who then was the grandfather of the Francis Brown born c. 1610, died New Haven Connecticut... I just wanted to double check if there was a reason the interim steps were not Master Profiles and if those links can be assumed valid?"
"Geni linkages can be great when they go through verified MPs... I am not certain how seriously to take lineages that seem to show up in multiple places across multiple ancestry sites, but have missing "official" curator stamp of approvals for an early American lineage in the middle..."
End of Message
Amen. Let's work together to keep improving the Geni tree in this important early American historical area. That means either researched and SOURCED MPs or detaching unproven parents that were hypothesized as part of the late 19th century vanity genealogy hobby.
