Great advice !
I've learned to ignore the "amateur internet researchers".
No doubt they mean well, and aren't trying to mislead anyone.
But they tend to jump to conclusions when they see something on popular ancestry sites.
I've learned to focus on family stories, family Bibles, and such.
Family legends are also worth looking into.
Many of my ancestors had the same
Christian name/ First name . . . and it's also common that
Surnames/ "Last Names"
were often misspelled in official records.
That drove me crazy !
Plus, 25 guys named William, 30 guys named James or John . . . all of em' with our surname.
I was ready to quit myself.
I have the same issue with some lines on my mothers side. It can be a pain in the neck.
