Combined info from TX Dth Idx Online and SSDI:

As for the sister Pauline, did she ever marry?If not, I don't think she was in TX.From SSDI:
Pauline E. Zent, b 1919; d Jul 1993; last residence Fort Wayne, Allen Co, IN; SS card issued in IN.
I am assuming the Lawson J. Zent, b 1911, d 1997, last residence in IN, and Virginia Zent, b 1911, d 1979 with last residence in exact same town and county in IN as Lawson are your family.You did not include any dates, or approximate dates, in your query.Nor, any locations, but, I think you need to use the IN forum.
