I would suspect that the middle initial on the first city directory entry was incorrect. The addresses on the first and second entries were just a couple of blocks apart. And no, there was nothing shown for Eagle in the city directory - that was a rural area then and the directory just showed property owners. One thing I didn't check at the Idaho History Center was to see if the Ada County death records are on microfilm. Some counties recorded deaths before there was a state requirement to do so (1911).
