ha!
Historical serendipity strikes again. I chose Antony’s ward more or less at random; basically I decided to put him on Lombard Street, which meant either Langbourn or Candlewick, and I chose the former. Turns out — if I’m correctly translating from a modern map of ward boundaries; King William Street wasn’t there back then — the first City plague death in 1665 was in Antony’s ward.
I should double-check this in Stow, but not tonight.
