In the Mount mailing list on Rootsweb, there is an archived email which shows Catherine Bogenreiff as the wife of John Mountz. John, born about 1742, was the son of Jacob Mountz and Maria Catherine Lauck. I have not personally seen a marriage record for John and Catherine, but I have verified much of the information in the archived email. Contact me directly for additional Mountz information.
