In early summer five years ago, we were sitting shiva for my father, the poet Aryeh Sivan. At 3 P.M., one day midweek, the stream of visitors paying their condolences had thinned out, and my curiosity turned to my family history. I googled the name of my paternal grandfather, Chaim Bomstein, without really knowing what I expected to find. Grandpa died in 1950, long before the invention of the internet. He never even had the opportunity to see television. But who knows? The internet is packed with intriguing bits of information.
