I've been trying to do some research on Louis Stauff, GrandMary's father. So far, the one of the most interesting things I have found is this wedding notice. Stauff is actually only mentioned as an usher--but it is in the wedding of Granddaddy's parents.

BRENNAN - GANNON
A very charming church wedding took place this morning at 9:30 o'clock at St. Francis Desales church when Miss Nora C. Gannon, daughter of Mrs. Margaret Gannon, became the bride of William J. Brennan. The ceremony was performed by Rev. W. A. McDonald, rector, in the presence of a great many of the relatives and friends of the young people. During the celebration of the nuptial mass, John Chartres, organist, rendered several selections with the obligato by Frederick Henle. The children of St. Francis Desales School also sang, which added much to the impressiveness of the service. At the conclusion of the mass the rector made a few congratulatory remarks with best wishes for the future happiness of the couple. The bride looked charming in a white messaline gown, the bodice being trimmed with duchesse lace. She wore a tulle veil fastened to the coiffure with a white aigrette. Her bouquet was of bride roses. Miss May Gannon, sister of the bride, was maid of honor, and was attired in an extremely becoming pink messaline gown. She wore a dainty pink moire hat trimmed with plumes and roses. James W. Brennan, brother of the groom, acted as best man. The ushers were Messrs. Charles Hickey, Louis Stauff, John Neary and Edward McKenna. A reception was held at the home of the bride's mother at No. 40 North street. A breakfast was served afterwards to about fifty of the relatives and invited guests. At the house Chartres and Henle also furnished the music. Mr. and Mrs. Brennan left this afternoon for an eastern trip.
