What a fun story. Glad you answered the call.
I told this lady that she ought to work for the CIA. She had only my mother’s maiden name. Yet, she managed to find her obit, her married name, my name and phone number, her grave, the name of the school where she taught for more than 25+ years, the name of a book she wrote and published, a copy of that book (obscure), the addresss of where she grew up, where she lived, and where she died, all before she contacted me. She just wanted pictures and a few more details from me. Since then, she’s looked up records of the old Sierra Summer program run by Mom’s college and even found a picture of her there.
I plan to go back to my old home town for a class reunion sometime next year and hope to meet her in person.
