I just got my results and can see a map, a pie chart and lists of names and public trees with maybe similar... well, similar what? Similar DNA? SImilar original locations?

Anyway, all the pins in the map are there because I previously added a location to an ancestor. For example, there's a pin in Poland for a 2nd great grandfather. But I added that BEFORE I took the DNA test. What on that map, or in any result, is DNA rather than location-matching from my pre-DNA tree?
