No, I\'m afraid it isn\'t as it is slightly earlier... The name Wild West was contributed by Buffalo Bill and his \'circus\' and refers to the times long after the first settlement. So I think you need to concentrate on all those rascals and outlaws and other unpleasant blocks rather than on Indian love stories :-)
Try these guys:
Pat Garret, Billy the Kid, Sundance Kid, Butch Cassidy, Davy Crockett and the lady (ykhm...) Calamity Jane... and some events like OK Corall gunfight (Wyatt Earp and Co.) :-)
Movies may be another good resource in your search:
\'The Searchers\', \'The Good, the Bad and the Ugly\', \'Little Big Man\', \'High Noon\', \'Kill Bill\' - yeah, yeah - there wouldn\'t be this movie if it had not been for Sergio Leone... :-)
