Searching for Last Will and Testament, probate record, and/or deed transfers. John first appears in the tax records of North Sewickley, Beaver County, PA in 1815, and he continues to pay taxes on 400 acres of property in North Sewickley, Beaver County, PA until 1826. In 1827, John's son, Thomas, and John Yoho paid taxes on the 400 acres and John disappears (I am presuming because he died). I've not been able to locate Last Will and Testament, probate records, or deed transfer from his estate. I have, also, not been able to locate deed transfer for when John purchased the 400 acres in 1816.
