Pulaski was an intersex. So i guess the mustache in the photo was real. :)) Now, the DNA shows he's a intersex. So he's an intersex with woman's skeleton.
He never got married and had no children of his own.
Years ago, i' had visited a Polish culture and history museum in Chicago. They collected a lot of things related to Casimir Pulaski in the museum.
Here is a photo of his statue at Freedom Plaza in DC, seems that he's not big and tall "man" if the statue was made proportionally.
