I am searching for information regarding the three daughters of Robert Porter and his first wife Thelma Irene Wyer. The girls' names were Barbara Lois (b 1928), Marilyn Nadine (b 1933), and Shirley Mae (b 1935). I can find no references to the three girls after the 1940 census. I would like to know any information possible for them. Thelma was my grandmother's youngest sister. I would like to find information for that branch of my tree. Thank you.
