Problem navigating to a particular gravesite at St. Ann's Cemetery in Cranston, Rhode Island

I visited St. Ann's Catholic Cemetery this Sunday morning to locate the gravesite of a young man who died in a car accident in 1980 leaving his infant daughter and the mother behind. Although I have the lot number 1459 Section 35 I just could not find site. The problem is that St. Ann's management neglects to ADD the lot number to most gravesites. Making it cruelly impossible for investigators or non-relatives to find a burial site.V died on March 1, 1980. When I spotted gravesite 1398 I thought I must be somewhere near V's grave site. But no luck just more walking by the two or three Section 35 rows.
