Thanks for replying so quickly. Let me fill you in on what I know. I am researching my dad's side of the family who are Halligans as well. My dad is Kevin Halligan Born 1947. My grandfather was Thomas Patrick Halligan Born July 1917, we have no idea who my grandfathers father was,( we think maybe his first name was Patrick, because the name had been passed on) we know that he married Anastasia Chambers and she is the daughter of Anastasia Cody. How she is related to Buffalo Bill is unsure, we have heard that Anastasia Cody father was the brother of Buffalo Bill father. Or something like that.
