A note concerning the above writeup -
As the Count Florian von Banier was never married, any offspring of his, sons or daughters, would have been illegitimate and not heir to his estate. It is not unlikely that he sired a few children, especially during his time in Japan, but none of them would have carried his name.

The Count's line was formally continued in the form of an adoptive son and heir; a young kitchen boy from the pirate ship Sivka Burka, where von Banier served some time. Apparently the twelve year old Jerzy Fialkov made enough of an impression on the Count that he adopted him as a son (though the boy was only a few years younger than the Count.)

I don't know whether the son referred to above would be this adopted heir, or one of the many possible illegitimate sons.
