The irony of my search was that I was working and continue to work on finding the final resting place of Thomas Shaffrey McLaughlin. According to the Rockville Cemetery in Fairifield, California (Suisun Valley), only Alice M. Loney is buried there. There is no sign of Thomas S. McLaughlin despite my own family records that indicate he is interned at that location. I might need to check in Napa. Why wouldn't he be buried with his wife?
Anyway, as has become my habit, I have started including email correspondence in my online blog/journal so that it does not get lost in a drawer or in my Outlook folders. As always, living people and details of their current lives, are kept private.
Here's the first correspondence with Thomas S. McLaughlin's descendant that was sent to me found via Ancestry.com.
