The parade begins at 11 a.m., and an open house featuring bluegrass music will be from 1 to 8 p.m. at the post, at 126 E. Fourth St.
The American Legion post was first located in the Schenck Building, formerly the Busy Bee Craft Shop.
It was named after Russell McElfresh, the son of a farmer living in the Franklin area who was the first World War I casualty from Franklin.
McElfresh was killed at the Battle of Belleau Wood in 1918 and his body was returned home in 1920. He was laid to rest in Woodhill Cemetery in Middletown.
Franklin’s American Legion post then moved to the Alexander Building, now Landmark Cafe.
At that time, the Board of Education gave the Legion a building the school system had been using for classes. That building was moved to a lot on the Fourth Street hill, which was formerly a cemetery.
The present building was dedicated on April 16, 1966.
