You might try contacting the National Funeral Directors & Mortician's Association, Inc. (http://nfdma.com/district_officers.html) This is an African American organization with branches in the Los Angeles area. Also the Los Angeles Sentinel, the major African American newspaper
(http://www.losangelessentinel.com/index.html).
Also perhaps one of the major African American churches in LA such as First AME Church (www.famechurch.org) or Second Baptist Church
(http://www.sbcla.org/). I would think that among these sources someone would have some information for you. Good luck!
