I'm searching for info on my gr-grandfathers two brothers said to be living in the Detroit area in 1930. They are said to be James and Lawrence Perz. All were born in German-Poland. My gr-grandfather was John Perz born Jun.,1854,immigrated on the ship Fulda in 1884 to Philly,then left Philly for Angelica,Wi. Any help would be greatly appreciated. Thanks Mary
