I was listening to an interview today on Canadian public radio about the 100th Anniversary of the invention of air conditioning by Willis H. Carrier of Syracuse, NY, which is officially July 17, 2002. The person being interviewed was the current CEO of the Carrier A/C Company, still based in Syracuse. He seemed to be very knowledgeable about Willis and his story, so perhaps he could answer some of the other questions raised in this chain of postings.
Bringing up the 191 Carrier phone listings for NY State, I spotted 48 families living in Area Code 315 (Syracuse and area). Surely a number of these are somehow related to Willis.
