Asa Anthony Orr Johnson (13 November 2010 - 25 February 2011).
Update/clarification (27 February): In my sadness I fear I have mis-communicated. Asa was conceived last November (via IVF) and miscarried last week. Neither Susan nor I put much stock in the notion of an "unborn baby"; at just 17 weeks Asa was a promise as much as anything. But we had given Asa his name and our plans for the future had begun to orbit around the possibilities he held out. I am sorry to have mislead if I did; it was not my intent.
