William Sanborn - Alice

Dear Sir, What is the evidence for this Alice being a Sanborn? I was a founder of The Sanborn Family Association, and later served as the Genealogist, after my ex-wife had that job for several years. Neither of us has ever heard of an Alice in William Samborne's family, and none of the well-researched published sources mention such a person. Please be so kind as to share what hard evidence you have that such a person existed. Thank you.

It looks like the connection comes from an old Gedcom profile, I see (outdated) Wikitree notes in the profile for Alice Taylor I will shortly copy to an attached document:

Biography

This biography is a rough draft. It was auto-generated by a GEDCOM import and needs to be edited.

https://www.wikitree.com/wiki/Wells-224 Currently shows her parent less, and so will Geni shortly:

An old Gedcom file is no proof of anything, as I'm sure Erica knows, unless it specifies some real primary sources for the information. I still haven't seen or heard anything that proves this Alice person was a Sanborn. At this point, I don't believe it. And what's with this middle name of Wells at a time when virtually nobody had middle names? The whole thing looks very suspicious to me, a product of somebody's overactive imagination with a desire to "fill in every blank with a name."
