Looking for info on Berlin Alcancon Warren of La., Please.?

My wife's father was Wilton Berlin Warren (1919-2004) , Born Roseland ? LA. Died St Bernard Parish, LA. His Father was Berlin Alancon Warren (1882?-1956) Born St. Helena, LA. died 1956 Roseland Tangipahoa, LA. Berlin Alcanon Warren Married one Rosa Lea? Pevey. His mother's name is believed to be Amanda Ratliff. Berlin had a sister named Alice who married A Thames (Thomas) she had a daughter named Addie Thames (Thomas). We feel Berlin's Father might have been one Bill Warren. born about 1840. Unsure of this. Any help would be so appreciated. Asked once before but computer crashed and all answers were lost.
