Bill, I posted a request at the catholic cemetery web site that you suggested and struck gold!! Wilfred Holtzman was buried on March 19, 1952 in Section 39, Lot 369 in Calvary Cemetery. Rose Holtzman was buried on April 5, 1973 in Section 39, Lot 369 in Calvary Cemetery. Thank you so much Bill for pointing me in the right direction!!
Is it possible to check for obituaries for Wilfred and Rose that might answer the question if there were any children from this union?
