Talked to Commander Maro. He congratulated me and said I should be the one to destroy the DB. However, no map entry to find the DB lair and no quest put into log.
Tried Setstage DBDestroy stage 30 but the console claimed not recognized. The stage 30 is where I talk to Maro.
Any suggestions would be appreciated.

Hmm. Try a reload to just after you kill Astrid, then run through the whole thing again? I don't know if it has any effect - but I've only ever talked to guards in Solitude to "report" and never had any issues....

Appreciate the feed back, but that was so long ago, I guess I am just going to have to leave it. If I find out where, or stumble into the DB lair, I will kill 'em all and then go back to see Maro and hope for the best.

Well, I can tell you appx. where the lair is, but I'm wondering if you even do this now if it will finish correctly. Seems like it's already bugged.... but if you want me to post the general vicinity, I can, or I can pm you?

Thanks for suggestion, Serethil. I will decline and just do my usual wandering and see what happens. Not major that I deal with them now.

Well, if you want some help, pm me or post back here. Though, considering that I've been in the area on toons who do NOT have the quest yet, and the Sanctuary is definitely NOT THERE, if it's not showing as a quest I wouldn't bet on you finding it even with the location. Good luck!

Well, strangely enough, after communicating here with you, I started playing the game again. NOW the arrow to the lair W of Falkreath has show up. You must have communicated telepathically with my computer--And I am in Thailand (with a real copy of the game that is authorized for Thailand. Only one store in Bangkok will carry real product.

Wow. I had NO IDEA I was that good! *laughing* Have fun!
