Finding Father in Nursing Home?

My Father had a stroke several years ago, while I was busy handling all his affairs (obtained SSA, got placement in VA facility which specializes in Stroke patients, cleared out his home and put everything in storage, shut off and cleared up all his bills), his 21 year old, spoiled, selfish, snot nosed Son (my half brother) with the assistance of his Mother, by Fathers EX wife, obtained Power of Attorney behind my back, by accusing me of stealing (my Father owned nothing) and attempted to have me arrested, and was awarded full custody of my Dad. I had a nervous (emotional) breakdown, and was lead to believe my Father had passed. I just found out he is alive, in a nursing or convelecent home, I just dont know how to find him. I have a general idea which city. any suggestions?
