#defaultView:Map SELECT ?item ?itemLabel ?district ?districtLabel ?coords ?FindaGrave WHERE { ?item wdt:P31 wd:Q39614. ?item wdt:P17 wd:Q664 . ?item wdt:P131 ?district. SERVICE wikibase:label { bd:serviceParam wikibase:language "en" . ?item rdfs:label ?itemLabel . ?district rdfs:label ?districtLabel .} optional {?item wdt:P625 ?coords.} optional {?item wdt:P2025 ?FindaGrave.} filter(!strstarts(?itemLabel,"Burial")) filter(!strstarts(?itemLabel,"Midden")) filter (?item NOT IN (wd:Q79309412, wd:Q79309112, wd:Q79309436, wd:Q79311062, wd:Q23073922)) } order by ?districtLabel ?itemLabel
