The following information was obtained from the German Evangelical Protestant Church records, Pittsburgh, Pa. I have no idea as to how it may relate to your inquiry but trust that it may prove helpful in your research;
"Gaub, Joh., von heir, was on 5, May 1885 married with Katharina Emilie Tittlebach. Sponsors: Maria Tittlebach"
"Gaub, Blanche Emilie, born 17, October 1888, child of Johann Gaub and Katharina Emilie born Tittelbach. Died: 14, July 1889 6 a.m. Buried 15, July 1889 2 p.m."
(I assume that the burial was made in Zimmerman's Cemetery, 2511 Brownsville Road, Pittsburgh, PA.)
