I found an Edgar Ray Huie born 1920 in AR and Jewel Gaddis Huie born 1926 in AR buried in Smith Mt. Cemetery also. They could have been William L. Huie's parents.
I also found the following death record for a Wm. L. Huie in Conway Co., AR.
Web: Arkansas, Find A Grave Index, 1819-2011
Name: William Lee Huie
Birth Date: 21 Jul 1941
Age at Death: 64
Death Date: 28 Jul 2005
Burial Place: Plumerville, Conway County, Arkansas, USA
Could this be where William L. Huie ended up?
I can't find anything on Phyllis Rose Pack with the exception of what has been posed here. I'm wondering if Lisa Gale Huie Blakemore isn't the oldest daughter of William and Rose as she was born in 1965 and they married in 1962 although Lisa was born in Conway, AR by her obit and they were married in CA in 1966. Maybe he had Lisa by a previous wife. Too many unanswered questions.
