Even at five years of age it appears that William Palmer loved horses.

In the 1935 book Palmer The Rugeley Poisoner by Dudley Barker it is stated that two years before his book was written this unsigned watercolour was inherited by Mr. Bernard Woollaston, of Stafford. He was the great-grand-nephew of Superintendent Woollaston who was responsible for Palmer's safe custody during his trial at the Old Bailey. Woollaston also inherited the Jane Letters and Palmer's death mask.

Probably the most scandalous memorabilia is the collection of love letters written, in 1855, by Palmer to a lady known only as Jane. For further details see Palmer blackmailed and the link to the Jane Letters. Below is a photograph of the first and fourth side of the folded note.

In the William Salt Library there are a number of pamphlets and sermons relating to Palmer dating from the 1856. For details of the material available see the For further study - William Salt.
