I don't know if this might be a start to further interest those of us who still might have family in Washington Park, but I am going to list my names here still known to be at Washington Park Cemetery
Ed Vance..

died 11 May 1929 St Louis Mo
last know address, 2204 Randolph St Louis Mo

Eugenia Vance Agnew/Agnue
born abt 1883 MS

last known address was E.St Louis Ill.

Annie Vance Jackson born abt 25 Oct 1891

Maybe if a list of this sort was published by families who still know about members still buried there, to the public, it would help get people to donate. And it also may help us family historians, to find cousins in or out of the state. You just never know what doors will open.
