I don't think this website's information is of much value. Not only are the maps out dated by at least 5 years, but in the case of my old house, it shows my late wife's name and she died over 4.5 years ago? It does not even show that my 2 year old new house or the street extension even exists, but provides a name to my address which is not me, not on my street, nor even my house?
If you lived in your current house for more than 5 years, there might be some degree of validity in getting your wife's name right. There are other websites that are far more accurate and up to date.
If someone was stalking you or your spouse, they would probably rely on a different website to provide more accurate information than this website provides.
