I got all of this from Mr. von Husen, a teacher and local historian in Lemfoerde. He is familiar with the City of Lemfoerde and sent me all of this information for your use. All I did was translating that.
He is interested what you know about this persons and how their emigration took place, and how they came around later in Texas. As he's said, he is interested in old photo's, so when you have those you should send some copies.
Hope all of this information is welcome,
Wilhelm
P.s. Robert's comments gave me the idea to ask for help in Lemfoerde .
