Here are the last four members of the Defenders of the Manor from Siberia Miniatures. These are the remaining family members, including the matriarch of the family, the youngest children, and the husband of one of the daughters.
These two children are dressed in sailor suits, which was common for upper class kids from the late nineteenth and early twentieth centuries.
Now to finish up, here is a gentleman, probably the husband of one of the daughters. Maybe a lawyer, or banker.
