To be honest, I don't know her name. I got the picture from another freeper, but I think she IS a cowgirl.
She's my freeper friend's and my mascot, so to speak.
Also, the anonymous lady is dressed in a later fashion, probably around 1910-1915 from the corsets and style of the hat. Annie Oakley was born in 1860 and was active with Buffalo Bill's show from 1885 until severely injured in a train wreck in 1901, she did recover and did some limited touring thereafter, but the height of her career was before the turn of the century.
