@Piipriker - I tend to agree with your assessment. It looks to me like many hand drawn items I've come across in family histories. With the OP saying that his Herres family has been in Germany for so many generations I think it is a stretch to link it to the Scottish surname of Herries.

It almost seems that whoever made the drawing may just have been having some fun pulling elements from Heraldic Achievements from possibly English and Scottish origins.

The Herries in Scotland are still to this day heavily concentrated in Dumfries but unless the OP can find a link to that area it seems a tenuous connection.

All fun just the same.
