Yes Andrew, sadly most of what passes for the massively propagated genealogy this days is utter nonsense.
There is a race between better source proof being provided more readily to everyone, and exponentially growing garbage propagation overwhelming those source proofs.
It dismays me to see my distant relatives taking my old working files that have fallen into their hands, and then simply tossing it up on to the Internet, where it gets propagated again and again as fact. In most cases they then completely walk away from it, so that errors never get corrected, and it appears as if the origination came from them.
I have not yet had the unpleasant experiences of one of these proagators telling me that my correction is wrong, because the file came from their close genealogist aunt (thus missing my early role in the creation). but I suppose that is coming.
But I have had the unpleasant experience of somebody completely detaching individuals from one of my created family branches, because it did not agree with their own incomplete propagated data, despite the fact that I had the full family spelled out in the census records on the profile bio. So it goes.
As far as the Family Connector tool, I discount anything beyond 10 degrees or so, as likely having at least one error in the path which would make it faulty. Each degree further has a mathematical certainty of exponential increase in such errors, such that at 40 or so degrees the specified path is certainly wrong in every case.
But that is a whole other can of worms. At concern here is merely that a connection has been made, and the *proof* that I mean is merely proof of the connection having been made, which is simply visible in the presence of the degrees of removal box. So it provides a starting point by which to then trace down and actually *prove* every stated connection, rather than hunting around endlessly for *some* connection somewhere.
That last is a bit troublesome, because it requires filling out countless siblings and spouses and parents and children of siblings, in order to find at least one connecting path. Many of those paths lead nowhere productive, and they grow exponentially with each profile to search through. So having an existing connection trail, even if faulty, makes the task that much simpler.
