Hi Paul,
You might find this useful. Double Stars by constellation at the Eagle Creek Observatory website.
http://www.eaglecreekobservatory.org/eco/doubles/
If you are having trouble with the name of the double, you might be able to pin it down by coordinates or the magnitudes and separations of the components. If you click on the name (left column), it will give you a direct link to SIMBAD which lists all its identifiers.
Regards, Rob
