Theodoroff is very common family name in Bulgariia. Theodor -too. To find details about him and eventually to find his alive relatives in Bulgaria I need his middle initial and his DOB. I believe that you could find them among emmigration and naturalisation registers in the USA. Orhanie is the old name until 1934 of today Botevgrad. Grace and Benjamin are not BG names at all. However you could try to find detials such as above about these people in the mentioned registers too. If you do, you could send me these details on alexbul (at) hotmail (dot) com. I will try to help.
