Monday's Madness Ancestor that became a Black Sheep, well Maybe. Harvey Edward FOULK

Way long ago a JOHN FOLK fought in the Rev War. He had children, my my, yes he did. HE died in 1793 in Greenwich Township, Berks Co PA. I have his WILL.
His son Peter Sr was born in 1773 in Berks Co we believe. He dies Perry Co. PA 1823.
His son Peter Jr was born in Perry Co. PA and married Susanah Martin Showalter, and they had William Henry,
b 22 Feb 1846 in Somerset Co PA. Died 4 Jan 1940 Cedar Township Blackhawk Co. IA. aged 93.

His son Harvey Edward Foulk, was born 18 October 1867 in Illinois. His family moved to Waterloo, IA Washburn area. His life was spent there until sometime in the mid to late 1930's. Family as I understand still lives in the house.

But Harvey sold wheat to Russia and disappeared. Family situation was not good and I suspect he left for greener pastures maybe. Family implied he went with wheat to Russia, others said he went to Australia. BUT he went somewhere, for no one seen or heard from him since. I am looking for where he went. DID he have more family?

He has become my big black sheep for Monday's Madness.
