I don't follow how the public record information here has any bearing on your house's marketability. What you see on Trulia today will be overwritten by the data your agent enters when your house is actively listed for sale.
Trulia's info is usually a reflection of what's on tax records. Why don't you take a look at what your local county lists for your house? You should be able to access that via the Greene county's assessor's webpage.
