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.

Mwoo hah, got it!
1) Some have reported you saying that we have already been given enough evidence to determine Harry's age. One point of contention is the real-life timeline of David Copperfield, who only adopted that stage name in 1974 and gained national recognition in 1977. Did you have these dates in mind when you named Harry, and if so, does this give us an upper limit on Harry's age? Is the smallpox vaccination scar also meant to be a clue?
Some, kind of, and yes.

Harry's dad was acquainted with DC from the SAM when both were at a similar point in their careers--just getting going. Malcolm was a bit older and more experienced, but didn't have the same kind of raw talent and had not had any major success or anything. Malcolm had an enormous amount of admiration for the young performer (and may or may not have contributed the notion for his stage name).
2) How long was Harry in Chicago before opening his detective business, and how long did he work with Nick at Fallen Angel? (Also, can we get a last name for Nick?)
Harry was in Chicago for most of two years before he started working with Nick. He spent three years at Ragged Angel. Nick's full name is Nicholas Christian, and he was the protagonist of three or four short stories I wrote when I was even more ignorant about writing and storytelling--and was in fact my "original" prototype for Harry Dresden. No wizard stuff or anything, just sluething and savvy, a little karate and a gun.
3) How long was Harry with Ebenezar? Was there much intervening time between when he left Ebenezar and when he moved to Chicago? (Yeah, so #2 and #3 together are tantamount to asking "How old is Harry in
Storm Front?" Was it that obvious?

)
Harry was with Ebenezar for nearly three years, from sometime not too long after his 16th birthday until his 19th or so. He roamed around for a while before winding up in Chicago, but it wasn't Children of Israel In The Desert roaming or anything. Call it somewhere between nine and twenty months.
4) Did you happen to have any point in time in mind for "Vignette," the short story in which Harry and Bob discuss his yellow pages ad?
Not particularly.

5) Care to pin down specific years for the actual books so we don't have to rely on my ridiculous BSF/ASF system? *puppy dog eyes*
See above answer.

6) Sorry, after the revelations at Dragon*Con, I had to add a sixth. You spoke of the age difference between Molly and Daniel as being part of the reason Molly will be the only magical Carpenter kid. However, Molly is 17 in Proven Guilty, whereas Daniel is about 15 or 16, "maybe old enough to take a driver's test." There's not much of an age difference at all. Should I get a life?
Always!

But what's critical to this particular equation is the fact that Charity was consciously and deliberately neglecting her talent--which hadn't been all THAT hot to begin with. She went through the time she got engaged to Michael, all the way through Molly's term, all the intervening time, etc, before she got to Daniel. It had been more than two, maybe three years since she'd done anything with her magic by the time Daniel was conceived.
About how old is Alicia Carpenter in Proven Guilty? We're given approximate ages for all the kids but her.
Uh. Hsm. My notes are buried under about six weeks of "I'll get to it in a bit" work that's been accumulating (of which answering questions here is some!). I'll try to find it.

But the Carpenter kids' births are all pretty much within six months of being annual occurances.
What is Richard's (Murph's second husband's) last name?
Boughton.

Care to give us approximate ages for Luccio and Morgan?
Morgan was born fairly late in the 19th century, and fought for Britain in the Great War. Luccio can barely remember the War of 1812 (which puts her in the same category with most modern American students), but it was of no interest to her at the time, growing up in southern Italy.
And finally, I know you're extraordinarily busy, but if you happen to glance over
our timeline and notice any glaring errors, please point them out!
No promises! I still have the next Furies book to hammer out!
