Shelia Jack is correct on their keeping your money as a search fee if they did not find it. BUT if you go there in person...I have always been told by them to keep my receipt and there is no expiration date on it but can show it to gain another search if I find more information to help them locate the document. If you are on the north end of town take I 44 to the Lincoln Blvd exit. On the south end of OKC take I 40 to I 235 and go north this too will take you to Lincoln Blvd. Just as Jack said the Historical Society sets on the south east corner of the capitol building (which set in the middle of Lincoln Blvd such as a town square so if you are coming from the north you will have to turn at the stop light south of the capitol anc cross over to go back north for the turn to the society) There is a sign at the edge of the road that says OK Historical Society and Veterans Memorial but you have to watch for it. The OK Health Dept is located at 1000 NE 10th as Jack said...and 10th is south of the capitol - historical society and you will turn east off of Lincoln Blvd and abt a block down you will turn right (south) into the parking garage. For those who don't know OK Historical Society will have a new home in the next couple of years. It will be near the governors mansion. Good luck in your search! Kathy Stokes Hudson
