Call from New Zealand

I am asking for help. We received a phone call from a young man in New Zealand last week. Due to land line issues we were disconnected before I could get his name and number. Apparently his sister found Carter on the internet somewhere and gave her brother the information to contact me. Carter and this young man share many things in common. Im hoping however his sister found me the 1st time she will do it again and let her brother know that I would very much like to talk to him again.
