Thanks to all who responded, Lucy, I agree up to a point. Sarge and above I get, but I have never seen an old document that ever listed a private, including documents (wills, estate records, deeds, court minutes). I have several of these in my line, Patriot and Confederate service, private almost to a man, but they never used the rank. I have seen records with Capt. as a prefix for some others related to me.
My dad served in the United States Navy during WW II as a Seaman. He never used the rank after the war. He also served during the Korean Conflict as a 2nd Lt. in the United States Army, and he never used that either.
I’m going to guess this shouldn’t be an issue. I think it should be included in the bio, but I also believe that there is enough latitude here to use a personal preference. I was only wondering if WT had an official policy in Style for this kind of situation.
Sargeant Selvaggio-Diaz, I salute you for your service and honor you for you commitment to your country. (BTW: you have a magnificent surname!)
