We recently purchased property in Victoria, Texas for constructing a mission Church. On the land were white bricks buried by a creek. The bricks were impressed with 'LAD. FALCON MEXICO' in the frog. Any information about their origin/history would be appreciated. The land was Spanish land grant property deeded to the O'Conner family, then sold to one of their emancipated slaves in the late 1800's, the Sheffields, and now to our Church group. We're thinking of incorporating the brick in part of the Church structure. Thanks for any guidence.
