Hi , I've been researching Schroeders in Cleveland . The cencus for 1850-1880 is nearly all german in the area just west of 25th , around Lorain Rd . ,Near the West Side Market . I think it is Wards 8,9,10,11 depending on the year . If you're local , Fairview Park Library has a lot of records on Cuyahoga Co on site . Good Luck .
