I really don't know, but, of course, I'll give you an answer, anyway.
Helen's full name was Helen Camp. She was the original owner, but when the papers were filed, they asked for "Last Name, First Name, Middle Initial," so she wrote "Camp, Helen NMI," and for many years after her death, the property was known as Camp Helen NMI, but when the Comers shelled out a little pocket change for the property 'WAY back before The Andalusian Era --- as my Mama always said --- they thought it meant "Camp Helen IN Michigan, so they decided to change the name to Camp Helen NFL, but the National Football League protested, so they just dropped that, and the place became known simply as "Camp Helen, Florida."
There WAS a Helen in the Comer family. If you dig deep enough into the family history, she's there.
I remember reading her name once in a Comer article....
Update on Camp Helen name: Named after Helen Comer (nee Browne), who was Braxon Bragg Comer's daughter-in-law. She was married to John Fletcher Comer, one of Braxton Bragg's sons, of course....
