3rd cousin to British actress, Jean Marsh O.B.E., co-creator of the TV series, "Upstairs, Downstairs". They share a Great-Great Grandfather, Timothy Oliver, of Blackfriars, London, who has recently come under investigation as one of the persons on whom Charles Dickens may have based the character of Tiny Tim, in the 1843 novella, "A Christmas Carol". Marsh's mother's middle name, Susannah Nightingale, was the maiden name of Timothy Oliver's mother.
