Hi Dave: A minor point about the last residence of Thomas and Violet Borthwick. It's Lakehurst, New Jersey--next door to the Naval Air Station where the German airship Hindenburg caught fire.
I checked burial records of a few cemeteries in Ocean County, New Jersey but found no Borthwicks buried there.
You can go to the following url for the Ocean County, New Jersey page of the USGenweb Project for links to cemeteries and other resources
http://www.rootsweb.ancestry.com/~njocean/research.html I checked MSN White Pages and found Borthwicks currently living in Manchester Township, Ocean County. Manchester Township surrounds Lakehurst.

P.S. Hope you had an enjoyable time at the Glasgow Meet. I wanted to come, but living on the wrong side of the Atlantic (70 miles or so northeast of Lakehurst, NJ) makes it difficult. Next time, I have the perfect group activity for the folks who show up: finding my great grandfather Robert Hendry. His wife was raised in Bridgeton on what used to be called Adelphi St. and is now Muslin or Poplin St. I think he was in Glasgow too.
