Dr. Conrad Murray wasn't just Michael Jackson's personal physician -- he treated Michael's children as well.

Matt Alford, Murray's attorney, tells TMZ Murray met Jackson back in 2006 and treated Jackson for "various illnesses." Alford says Murray cared for Jackson's kids from time to time as well.

As for suggestions Murray did not perform CPR correctly on Jackson, Alford said he doesn't know why Murray did it on the bed instead of the floor.
