Need help tracing some email addresses

[Eresf83]

I've been trying to track down a person that has been hacking into my system about a year now. After endless amounts of network logs & netstat reports I came across two email addresses that were remotely connected to my system. Now I need help researching them further...any suggestions??

It's only one that I need to find its origin and it's owner if possible

Is there a company that can assist or is there a system I can use

Thanks
