Sibling Saturday - Maime Gaisford

My Great Grandma Cora had an older sister, Mary Ann or "Maime", who never married or had any children.  She lived with her parents until they passed away.  Sorry to say, I know very little about her.

"Miss Gaisford Is Honored On Birthday   

A surprise party was given Friday afternoon from two to five at the home of Mrs. Ervin Schuette, 1310 Grant, by Mrs. Schuette and her sister, Mrs. Lester J. Reed of Byron, honoring their aunt, Miss Mamie Gaisford's 78th birthday which was Saturday, Jan. 24.

Present were Mrs. Harlan Weaver, Mrs. Clarence Mann, Mrs. Emma Baker, Miss Chloe Bartlett of Beatrice, Mrs. Frank Amos, Mrs. Maude Hemphill, Mrs. Nellie Rathbun, Mrs. Harry Foster, Mrs. Louie Langworthy, Mrs. Will Gaisford, Mrs. Rulo Rathbun and Jeanette, Mrs. Nellie Griffin of Ellis and Mrs. Hugo Schuette of Diller. 

During the afternoon, Mrs. Reed played several piano selections.  Miss Gaisford was the recipient of many cards and gifts.  At the close of the afternoon a lunch was served."  [* Source:  Beatrice Daily Sun, January 29, 1948]   

What I want to know is why do they sometimes use the married females first name and other times use the husband's name, even within the same article?
