Ed, AHA!! May have this figured out and it does fall into the category of the parallel universe.........
In 1950 directory listing - 3 DIERS listed
Billy J. With wife KathD. Salesman. H. Cook Sporting Goods Living at 463 Loma Hermosa. ( Wife seen as KathD, Kathyrn. Kathy G)
RW With wife Mary E , in Sales working at Central Typewriter. Living at RD4 Box 689
Wm J with wife Ruby working at Central Typewiter. Living at RD4 Box 689
William James, "Billy" sometimes seen as B.J. , Billy James Dier
b. December 1917 Died July 16 1993 .
Billy also lived @ 8575 Flower Pl NE.
I can find no connection between the 2 families.
In a wedding announcement in The Albuquerque Journal for Billy's daughter, grandparents and aunt/uncle listed.... Nothing familiar there.
I think "my William's " son, Roger , is mentioned many times in sports for Albuquerque High Bulldogs 1940-1942. Apparently a basketball star player
"My William " Veteran grave marker application was signed by wife Ruby and indicated he served in " KS Sgt 117 Field Sig Bn 42 Division WW1". This corresponds with my grandfather miltary history (who is coincidentally or not !! Is the BIL to William's 1st wife, Mabel).
"My William " also had a long history of working for Remington Typewriter.
Began in Kansas City before WW1 where he worked with my grandfather for Remington. So all that part fits in as well.
Still looking ........Can't find Billy with Elizabeth and first 2 of their children in 1930 in KY yet.
Maybe Billy did not marry Elizabeth until after 1926 ????
Is this mystery managed ??? Tho' still not finding William and Ruby in 1940 so not quite solved !!
