Calvery's location in Darnell supports those 2 guys' being Lovelady and Shelley

[Tom Graves]

Gloria Calvery is the largish/tall woman to the immediate left of Templin.

A slice of her lighter-colored plaid skirt is visible in a Couch-Darnell frame as she's standing on a lower TSBD step and to the immediate left of her dressed-in-all-white South-West Publishing Company colleague (Karan Hicks or Carol Reed), who can also be seen in the Zapruder frame, above, standing two people to the left of Calvery.

Factoid: The famous "Running Woman" on the Elm Street Extension in Couch-Darnell is the gal who's wearing the red headscarf and standing to the immediate left of Calvery. It's pretty obvious that she (Karan Hicks or Carol Reed) either removed her headscarf, or it fell off while she was running.

PS That's "I've Got a Weak Memory but I'm Quite the Embellisher After Fifty Years" Karen Westbrook Scranton standing to the immediate left of Gal-Dressed-All-In-White.
