I thought this may be of interest. I was reading through the online text of a book, Philadelphia in the World War, 1914-1919,
and found this statement, "The first British soldier to be buried in the United States in over one hundred years was Sergeant Malcolm MacFarlane of the recruiting mission, a veteran of a number of battles in Flanders who, stricken with pneumonia, died and was buried in Mt. Moriah Cemetery, where a beautiful tombstone marks his last resting place."
Here is a link to MacFarlane's record on Find A Grave, with a nice remembrance to him by the woman who recorded his grave, as well as a couple of pics (might be nice if members left some of the virtual flowers and a note--must register to do so, however):
