Celebrating the Fourth in 1913, a reading of the Declaration perhaps?, in an antique uniform, sadly since vanished (except for the sword).  Who all is involved, I couldn’t quite say.  However, the moustache strongly suggests that the reader is William Webster Ellsworth.  He would be the natural choice, as the family’s elder statesman, a gifted orator, and descendant of those worthy Wolcott, Ellsworth, Webster…ad infinitum. 

I do like the parasol.  The house is just visible, today, where they are sitting is a shady garden bed.
