Blaylock was said to have suffered from headaches, and while in Tombstone, Arizona, she became addicted to laudanum, a then-common opiate and pain killer. It is not known exactly when Earp and Blaylock ended their relationship. Tombstone diarist George W. Parsons never mentioned seeing Earp and his next common-law wife, Josephine "Sadie" Marcus, together and neither did John Clum in his memoirs. Frank Waters wrote in "The Earp Brothers of Tombstone" of public fights between Sadie Marcus and Blaylock and how the affair was a public scandal. However, Waters' book has been criticized as biased for its negative portrayal of Wyatt Earp and for including details not mentioned in the original manuscript by Allie Earp (the common-law wife of Wyatt Earp's brother Virgil).
