"Arkham (born in 1890) is the only son of mentally-ill Elizabeth Arkham"
Actually I am curious, did they ever explained how Jeremiah is his nephew/grand-nephew (it seems to mostly be the latter at this point due to the sliding timescale) if "Serious House" establishes that he's an only child? Just saying I was making a family tree of the Arkham family of all the known generations and I'm really confused right now. Then again this is the Post-Crisis continuity we're talking about, in fact, the New 52 adds more confusion, but in a weird inversion of the sliding time scale, they made him older.
