Cant agree its Michael, as if you blow the obituary up which Jack is holding, it says the person name is "John Latham".
Is Desmond's bird Penny, called Penelope Latham, im not sure. It rings a bell tho.
I think it only reads J...... ....tham, which many believe to be Jeremy Bentham, either a new character or a moniker for a current character. Jeremy Bentham is a famous philosopher, which would follow suit with the naming of John Locke.
