Mr Ker Seymer's dog

Volume 1, page 5, sitting number 23.

Identified as 'M. Seymer's dog' in the Silvy daybooks [the 'M' stands for 'Monsieur' and is used instead of 'Mr' throughout the first volume], the dog was identified as 'Pilot' on the album page. He was almost certainly named after Mr Rochester's dog in Charlotte Brontë's Jane Eyre, first published in 1847.

There is a portrait of the dog's owner on the preceding page of the daybook (Volume 1, page 4, sitting number 18), where he is identified as 'M. Ker Seymer.' Sitting number 19 is Mrs Ker Seymer and sitting number 20 is Miss Ker Seymer.

The Mr Ker Seymer in question is the politician Henry Ker Seymer (1807-1864), the member of Parliament for Dorset.
