Just coincidentally, my husband's great great aunt married a Konecny, but in Moravia, not Bohemia. You said "came from" so I gather that they immigrated to the US. You can get better help from those of us who love the challenge by telling us where they immigrated to, their approximate birth dates, and point us to census records, etc. There are clues every so often, such as research done on other folks in the same town, who might have come from the same village as yours.
Vader Janes and Marie Asanad don't look like any Czech names I've ever seen, so maybe they are from a specific region. Hakle? Could it be Hakel? Vondra, Jasa, and Navratil are common names every where.
