My son's father is Rowlland Allcie Vialva and Rowlland's mother was Albertina Juanita Houlder Vialva. I am trying to find immigration information on my son's father and any information on the rest of his relatives. My son is Christopher Andre Vialva, born 10 May 80 to Lisa Dickson and Rowlland Vialva in San Antonio, Texas. Please contact me if you have any information that would be helpful in my search.
