I believe it's from the JB forums, which can't be accessed if you aren't a member. However, a repository of Words of God has the transcript for you to check (search the quote box starting with: As the maintainer of the timeline, I have a bunch of timeline-related questions! Feel free to ignore or mock any question you don't feel like answering.)

The series of Q&A is also from where we know Harry's dad met David Copperfield, how long Harry was in Chicago and how long he worked under Nick, and when, approximately, Luccio and Morgan were born.

Anyway, here is the question and answer relevant to your query: What is Richard's (Murph's second husband's) last name? Boughton.
