Also, this branch of Markhams came from
Scotland, I'm not sure of the dates.
Edwin
Markham was famous as a poet. He wrote "The Man With the
Hoe" (after the painting of the same name) and also this:
He drew a circle to shut me out
Heretic, rebel a thing to flout
But Love and I had the wit to win
We drew a circle that took him in.
So even if you don't have certainty, claim his as a relative, he wouldn't mind.
