I serendipitously came up with your query; have you made any headway?
There are tons of Terans in AZ where I come from (actually we'refrom Sonora); my mother and my 8 siblings all live there, mostly in Tucson. We come from Sonora (Moctezuma, Nacozari) and have been moving north (with every major crisis, you may say). Anyway, I'm here, in New York City, where I work in the securities industry. Send me a note, and we'll take it from there.
