Agree with you totally, Edward Scott. We always should check things out properly, and not grasp at "it must be..."
I'm certainly not above having a look at trees that seem to have one of my bodies in it .... sometimes it's likely, and worth checking up a bit, often it's laughable, and/or careless clicking on alternatives ( that can so often shift people to the U.S.A., I've noticed) and usually it's merely another poor soul with the same name and approximate age, but different parents, siblings, spouse(s) and offspring that "A" has thrown up!
It's not worth getting worked up about. If it does seem like a likely fact, or possible connection, then I'm not too stiff-necked to try and check it out PROPERLY.
One time, a couple of years ago, I found that I'd made an error myself, two very similar folk, same name, approximate same age, and spouse name, and area born / lived in .... and when the 1939 register came, it showed me the chap's actual birth date, which wasn't what I'd got down. But it was him, I knew from family ... so I went back, and eventually - a few miles away, found the right chap, with his correct parentage, and then had to trace that back, and undo the tangled web from the wrong chap!! My fault, actually, and taught me to always keep on checking.
