USGS topos don't have church names, in my experience. When I look up
local churches I see the following two sources:
Citation: White Pages Telephone Directory. www.whitepages.com. Use Form
Citation: Southern Bell, Greater Orlando Yellow Pages, including Apopka,
East Orange, Lake Buena Vista, Montverde, Oviedo, Reedy Creek,
Windermere, Winter Garden, Winter Park and other nearby communities,
Bell South Advertising and Publishing Corporation, 1986, 1476 pp.
Contains listings of churches. p291
Presumably they used TIGER to geocode the addresses. I've seen some that
are in the right position for the address number but on the wrong side
of the zero line.
