Actually, if anyone did any reasearch into Mr. Holliman's background, they MAY realize that Mr.Holliman preferred to remain a bachelor because he didn't want to marry, father children, then die when the child is young, as not only his biological father and his adoptive father had done. His biological father died while his mother was pregnant with him, and having other children at home and scant income, his mother gave him up at birth. Then his adoptive father died when Holliman was 13.
It may simply be a case that Mr. Holliman feared the same happening to his wife and children should he marry.
I personally know people who have lived their lives in fear of what happened to them as children happening to their own children, so this is not so far fetched an idea in Mr. Holliman's case.
While I understand that "confirmed bachelor" has been code for being gay, it's also the correct term for men who are comoletely straight, but never chose to marry, for whatever reason.
And another little known or published fact, Mr. Holliman is a Republican and votes to the right.
Finally, let me wish you a Happy 90th Birthday, Mr. Holliman! May you have many more!
