Mom died Nov 13 at 94 years old.  In going through her things I found out that her father died on Dec 23.  I'd been missing the date. That's the same date my dad died on in 2014.  I also found that my Aunt Elizabeth remarried in 1981, but I have been unable to find any documentation of that or any further documentation of my aunt.

I did decide to go with the Find A Grave site for my Uncle Frank. The birth year on his grave was within one of the 1940 census, the year of his death is roughly right, he's listed as Frank G Morris - which is correct and he's buried in the same section as Aunt Mollie - his mother-in-law.

Found William Edward Magruder, Jr., his wife, and son.  All were on the Find A Grave site.
