I'm not sure which 'Logan' you specifically refer to. There could be many people named Logan. It could be a common name for an individual in a story, a character in a movie like 'Logan' where he is a mutant with a complex and tragic backstory involving his powers, his family, and his struggle in a world that often fears and hunts mutants. But without more context, it's hard to tell the full story.
Well, Deborah Logan isn't a completely true story. It's likely a blend of fictional elements and perhaps some loose ties to real-life situations or themes.
