I am attempting to locate my husband's family. At present the only information I have is that the Koenig once owned land in what is the city of Pittsburg. This would have been about 1850. Some of the family then moved north to Erie and Meadville, PA. I have checked in county for Pittsburg but have not located anything that would help. Would like to hear from anyone who might have some more information that might help. Thanks. Nancy
