It's been a while, have you found anything new? I do believe your Harley an my Harlan could very well be the same person.
My grandfather Tophel had a brother also named Harlan, they were the son of Herbert (whose brother ran away after their father William.'s death. We can only speculate, did his fathers death up set him to that point, or remarriage of his mother, I wonder if they ever heard from him again?
So many questions and very little information.
