To summarize - from the Happy File:

The blues' first radio star, legendary blues harmonicist Sonny Boy Williamson #2 (ie Aleck "Rice" Miller,) who probably taught Howlin' Wolf harmonica...

... probably was born 12/5/1899 in Glendora Mississippi. (He was also born in 1894, 1897, 1905, 1909, 1910 and 1912.) We believe he holds the record for the Most Often Born person in all the Happy archives.

(died 5/25/1965 [per Pete Welding] and also 6/23/1965)
