How do I contact owner of a property if all I have is their name?

[Steven Hoy]

I just recently bought a house and there is almost no yard, however, next door is an empty lot with some cement. It would make an ideal space for extra parking plus some yard space to go with the house. My realtor was able to find the name of the person that owns the lot. I was wondering if anyone knew how I could find the person's contact to make an offer? 

Any suggestions would be greatly appreciated!
