Maps are a wonderful addition. It would be added help if you can type in something to compare with what is showing to see how close they are.
Amen to this comment! I envision geographically based search filters, coupled with a time range selection, as having huge potential. In my case, I seek parents and beyond ancestors of an oldest known relative. Using list-based search, I can get a sense that others sharing that surname were IN THAT AREA, at around THE SAME TIME. Perhaps these people connect?! But to deduce that, I am constantly and laboriously checking a place name ... where is it on the map? Imagine, instead, being able to search on name (given, surname), time range, and then go to a map view where the result set is dynamically filtered as you zoom and pan!!! Click on or hover over the push-pins of the result set ... and accelerate your research a thousand-fold. Any takers on this idea?
Hm ... this is skirting dangerously close to all the problems with place names. We have problems using correct place names in the form of text. I suspect a huge number of mapping issues will result when you want to map someone born in Louisville, Virginia in 1780 or Nashville, North Carolina in 1790. What would you do with someone born in Seltz, Empire of Russia in 1853?
