Re: Hillberry, Graysville, Monroe Co
George Hockenberry/Hillberry was the brother of my great-great grandmother, Sarah (Hockenberry) Morrow.
If Elizabeth Jane Hillberry died in Graysville, I suspect she is also related -- Graysville was never a large community.
Sarah's husband, Marshall Morrow, served a term as Sheriff of Monroe County, about 1850. George's son, Laban Roberts Hillberry, was born in Graysville, Monroe Co, OH. LRH eventually moved in WY.
George and family settled in Richland Co, WI; Marshall and Sarah went to Dane Co, WI.
Most (probably all) children of both families were born in Monroe Co before they went west.
At least three DAR memberships and one SAR membership claim George and Sarah were children of James Hockenberry, a Revolutionary War Veteran from PA who died about 1844/5 is Morgantown, Marion Co, VA/WV.
