While the 1920 census shows Albert born about 1884 in Missouri, the 1930 census shows him born about 1887 in Illinois. Otherwise it really seems to be the same person though. In the 1910 census, he is shown living with his sister-in-law and future wife, and it shows him born about 1882 in Kansas. (So... born in the 1880s, location unknown??)
