Wolverine suffered from amnesia. As a result, what little was known about his early life was both suspect and unverifiable. It is believed that, at one point, Wolverine had a wife and child, but they were supposedly murdered by Sabretooth. As both Wolverine's and Sabretooth's memories had been tampered with in the past (most infamously by the Weapon X Project), this claim was highly suspect; however, Wolverine did own a wedding ring that served as his only link to his past.
