I am the daughter of Hortencia Sassenhagen, daughter of Arthur Sassenhagen II, son of Arthur Sassenhagen, son of August Schessenhagen.
I believe that my great-great-grandfather, August Schessenhagen, came to Texas from Germany sometime between 1880-1889, probably through Galveston port, and settled near Seguin, Texas. After they settled in Texas, the surname was changed to Sassenhagen. I also know that there are Sassenhagens that lived in Washington state. One of my uncles has told me that the family is originally from Frankfurt. I too am trying to trace family history, but have not done much at this point.
