I won't post a concrete address about this on a public forum but here is a tip that may help you on your hunt.. Usually the first place I would start for a private address would be to use a different name associated with the celebrity you are looking for. A family member who lives with Brian Doyle Murray for instance. Think about it and try to search. If you find it, don't give it away. If it gets out, you may ruin the address for both individuals.
I've always been against posting successes to private addresses for this reason. Its like a taunting brag where they obtained something you never will without begging for more info or taking your own chances. Although it can be a fun hint if you know how to hunt celebrities down yourself in general.
