AlexJordan on Family Tree Circles

I am interested in finding my old and current siblings and finally found a good place. My racial background includes Irish, Native American Crow, and Native American Blackfoot, and possibly German. The Irish surname I know of are Whidby. Almost anything that sounds like it could be related (I.e. O'Whidby, Widby, etc.). The Crow surname I know is Running Fawn. All the other surnames are Starky, Barnett, and Jordan.
Any help would be greatly appreciated!
