I'm looking for any information on my Urban relatives from Lower Silesia. Particularly Erich Urban, Kurt Urban and Gustav Adolf Urban. Gustav is my maternal great grandfather, born around 1870 in Altreichenau near Quolsdorf. Erich and Kurt would be my maternal great uncles, born around 1880. I don't know much else except that both served in World War I, and that Erich was wounded and sent to Kriegslazarett 54 to recover. He was still there at war's end
