In a last minute whirlwind that could only happen before the lovers were to be separated by the soldier's departure they promised undying love to one another. Tears were shed. The promise wouldn't die but so much could not be said for the soldier.
The parent's relief led to the girls stoic alienation. She knew her only hope to be reunited with her lost love was through death. In the dark of night she took her own life in this house and haunts it to this day.
If you walk around the house three times at midnight, the exact time she took her life, you will be able to hear her blood curdling scream to this day.
