I talked to Robert Weldon's wife, Dorothy this evening. She informed me that Nelda Estaline's husband, Wilson Alfinzo (middle name according to death index) was deceased. I found him in the death index: November 28, 1988 in Erath County, Texas.
Their daughter, Mary Ellen Bennett, never married, and died February 20, 1998 in Erath County, Texas. Nelda is still alive and lives in Mingus, Texas.
Aunt Dorothy said she would call me tomorrow afternoon and share more info with me.
