How to append property owner's mailing address to a list?

[Adam Hill]

I usually use Melissa Data to clean my list and obtain new information before purchasing direct mail. 

Recently, I obtained a list of 1,900 entries. This is a government obtained list in excel, like one could expect from a delinquent tax list, codes violation, or something that only references the property with issues not the mailing address of the property owner. 

My list has a property in question address, full name of the owner, APN (tax map and parcel), a map address, and longitude and latitude. 

Question: Is there some place like Melissa Data (I'm thinking they don't do this) where I could up load some of my information to get a correlating property owner mailing address appended to each entry for these properties? 

Looking these up 1-by-1 is not worth it. And  I'm not sure what % of the list is owner occupant. 

Any advice welcomed. 

Thanks
