It's been decades since I took a couple of years of Russian in college, but the letter Г was always pronounced has a hard G; never a soft G or H. On the other hand, Г, when it appears in a place name on Google Maps, is transliterated as H, which apparently is the official Belarusian style. Just wondering if this reflects long-standing differences in pronunciation; one of my father's uncles shows up as  Герц in what appears to be an 1894 census document (revision list?) but the passenger manifest showing his arrival at Ellis Island gives his name as Herz (and he was known in the US as Harry).
