As far as I can find, Jacob Castle took Sowegee, "Gliding Swan" as his wife somewhere in western Pennsylvania. She was from the Kisopoko sept of the Shawnne Indian nation. [The Kispoko sept is the same sept that the famous Indian warrior Tecumseh was born into.] Now, is there any official documentation of this, not that I can find. Not much was documented back then.
Here is what I have in file on her: Mary Elizabeth aka SOWEGE/SOWEGA or GLIDING Swan was born about 1710 in Pennsylvania. Sowege was a full blood Shawnee, Kispoko sept. She died before 1820 in Virginia.
Sowege was anglicanized and baptised in PA as Mary Elizabeth prior to them migrating to VA.

No census ever listed her name, as family memers did not get listed before 1850.

My information came from family lore passed down through the family and what info that we can find on Jacob while he lived in what is now Russel County Virginia. I [dlmeenach@aol.com]
