The Bundesarchiv is not the right archive, you will not find anything about him there.
Holsthum is a so called village-municipality in Rhineland-Palatine. May be that you can find there something about him in old files of the "Glaswerke" in the Rhineland-Palatine state archive.
The best way is to search in parish records. For that it is useful to know wether he was Catholic or Lutheran.
For Catholic records you can search on matricula, but I don't know if the records of the Posthum Catholic church are online there. I will look there later.
They put the Protestant records of the Rhineland online these days. I will look there later.
