Hello, I'm trying to learn any details about the uniform in the attached drawing. It is from my great-great grandfather (Adam Laubach) who emigrated from Germany (Nassau area). Family lore stated that he was a Prussian officer/soldier. He brought this drawing with him when he arrived in Texas in 1848, at which time he was 45 years old. Thus, I would surmise that the drawing was made sometime in the 1820's or 1830's. Thanks in advance for any info.
