Was looking at Crown Hill Cemetery's site and found a possible grave of Ezra Miller. The listing says," E. M. Miller d.15 May 1874, section 13, no marker, lot 46." Found it at www.crownhill.org/cgi-local/db_search.cgi
or you can email Crown Hill's genealogy dept. at firstname.lastname@example.org
. Crown Hill is located at 700 W. 38th St., Indianapolis, IN 46208.They have a great deal of information, but it is 5 dollars per search. Good luck!
