Not related to the main story here - I'm the first programmer in my family - but my great-grandfather was born in 1865 and lived a long life, he was blind for his last 30 or 40 years but had a phenomenal memory. A neighbor had the insight to use one of the very first tape recorders, just after WW2, together with my father who was a boy at that time, to record my great-grandfather's stories about what he did in life. When my father retired he cobbled together a working tape recorder from two or three old ones, and copied the stories over to cassette, and later to CD. I listened to one of those recordings the other day - my great-grandfather told about how when he as a young boy, approximately around 1872-1873, he met a very old man who told about how he had learned the origin of the name of where they (he and my great-grandfather) lived, from another man when he was a boy. That origin turned out to be very different from what everyone these days are guessing, but immensely more plausible. Brought to me from the 18th century, via my great-grandfather.
