Chris, I have searched some of the older cemeteries in this area and not found a Lantz in any of them. There are however two people with that last name living in Sherman. Christina Lantz 1601 E Fm 1417, Sherman, Texas. This is my address as well it is a Mobile Home Park called Shadow Mountain Village. I live at lot 9. The phone book does not give a lot number for Christina. Also Joseph Lantz address 1821 Timberline Ln Sherman, Texas. There is a web site for cemeteries in Texas. I was given this when I talked to a man at one of the cemeteries. The web site is
www.cemetery.state.tx.us/pub/database.htm I hope this helps you. I will find out from the manager of the mobile home park what lot Christina lives in and send that to you, because if you want to write to her you will need to know the lot number or they won't deliver mail. Debra P.S. Where are you from?
