Many history books say that she "dissapeared" sometime after Charlie's death, and there is one book in particular ("What Ever Happened to Billy the Kid", the story of John Miller) says that he (John Miller, a Billy the Kid claimant) married Manuela sometime after his "escape from Ft. Sumner.
yes manuuela hooked up with billy the kidd and moved to ramah NM and started a new life there. at miller canyon. all of the towns elders and families that have been there since the 1800's all know he was Billy the kidd. but these so called experts who have never lived in NM or even rode a horse or shoot a six shooter claim they are experts of the west what a crock. if you ever go to ramah go to the cafe and start up a conversation with one of the elders.
