The events spawning the leader pools will first try to place them in their faction's capital by name (Richmond or Washington), but only if they are still friendly held and no enemy units are adjacent; it doesn't matter whether they are still the capital, so I assume that although the capital has been moved to Atlanta, Richmond is still in Southern hands in your example.
If the above conditions are not met for Washington, then a Union-held city in Maryland is selected, the larger the city, the more likely it will be chosen. If that fails, then Philadelphia is selected, but also, only if in friendly hands. If none of those selections work, you do not get the leaders.
If Richmond cannot be selected per the above conditions Atlanta will be selected, but also only if in friendly hands and if not, the leaders will not be generated.
IF there were a faction-capital alias, it could be used to select the capital where ever it is, but there isn't, so you can't.
Beyond that, the events might be expanded to include New Orleans and New York for the South and the Union respectively if Atlanta and Philadelphia cannot be selected, but without a faction-capital alias I don't think there is a way to actually select the capital per se.
