Locate family members

[Brett's Honey]

Does anyone have any suggestions on how to start searching for family members that I have lost touch with? I would love to get in touch with my ex-stepmother and my two half-brothers that I haven't talked to since 1988. My Dad, John Melton (now deceased) married a lady named Rose in Wichita, KS in about 1982. She was about 26 yrs. old and was from Chicago. They had two sons, Jeffrey and Jimmy Melton. I heard that Rose may have possibly re-married and moved to Colorado, but I'm not certain about that. Her last name may no longer be Melton, and it's possible that the boys' last names have changed too. Since we last had contact, I've moved and re-married, so my name, address, and phone number have changed also. I would greatly appreciate any suggestions! I can't really afford to pay for a private investigator at this time, but I would like to go ahead and start searching now. Thanks!!
