Ok where he lived is pretty much downtown Los Angeles..
here is one I never even knew about...
Mausoleum of the Cathedral of Our Lady of the Angels
555 Temple Street, Los Angeles..(213) 680-5226
This mausoleum has 6000 crypts..and is across from St. Vibiana's which is one of the oldest churches in Los Angeles (it dates back to 1850 I believe)..it does not function as church now..as we now have
a very modern and new cathedral which Cardinal Mahoney presided..I don't know for sure but there is also St. Vincent's Church near by..across from USC campus
Anyway, both the above info is in the vicinity of where your
relative lived in 1904..that is including the other streets you mentioned..check these out..I have a few others but they
are further away from downtown Los Angeles...
