Hello all, I have a brick wall that's been bothering me for years. I cannot find my grandfather in the 1910 census for Cook Co. A thought just occurred to me though: GF was born at 1427 Byron Street in Chicago in 1905. In the 1910 census, his uncle is living at 1627 Byron St. did the numbers change in 1909/1911? My GF's name was Edwin RICKMAN, b. 1905 Chicago, son of Theodore Z., b. abt. 1883 Kentucky, and Adelaide RICKMAN, b. 1885 Chicago. Any help would be greatly appreciated. Thanks in advance, Donna
