When a property is sold by order of the Court of Common Pleas for debt or the County Treasurer for non-payment of taxes, the county sheriff becomes the Grantor of the property. The name of the original owner is not always mentioned in the recorded deed. If this is the case you should consult the Sheriff’s Deed Books for the information. The original owner is the person whose land has been taken or the defendant named in the debt case. Once you have obtained the name of the original owner you need to check the Grantee index.
Be sure to check the Township – Land Record Clippings at that the Chester County Historical Society. You may find a full description of the buildings published with the announcement of the sale.
