Inductive idiocy , freestyle BS. "It does not preclude...."
Who are you, Maury Povich? Geraldo?
"It does not preclude" Merryman's being a "crack screwsman", a space alien, a time traveler, Prince Albert in a can. What is this, Coast to Coast?
Does it?
Interestingly, I found a reference to a letter in reply to one from Anne Taney to her father, apparently informing him of the death(?) of "Mr. Bosley," in 1843. I might see if I can't get a copy of this correspondence. I suspect "Mr. Bosley" is Nicholas Merryman Bosley, John Merryman's uncle(?), who left him the Hayfields Estate when he died in 1843.
I wonder why Anne Taney thought that would be of interest to her father? I wonder why Roger B. was "shocked" at hearing about Bosley's death(?)? (Assuming Roger B. didn't know the Bosley/Merryman family, like you say.)
I might want to spend a little time on this, afterall.
