All I have is from the 1930 census that she was a nurse then: see below mostly pieced together from census data:
Franklin (Frank) Andrew Zeiders, b. 4 Mar 1890 Dimesville, Juniata Co., PA, d. 1921, m. ca 1907 Lottie Virginia Niemond (b. ca 1889, d. 1920, bur Niemonds Cem, Juniata Co., PA, d/o James Niemond & Mary J), 1900 census; she was living with her parents (without Franklin) with her 2 children in 1910 census & with only Geraldne in 1920 census), WWI draft card 5 Jun 1917; res Knowsetown, Juniata Co., PA, Machinist Burnham, Mifflin Co., PA, m. with 1 child, m. 2nd Dorothy Strickland Hartwell, children (i. & ii. by Lottie, iii. by Dorothy):
i. Bertram W Zeiders, b. 31 Jul 1907, d. 25 May 1915, bur Niemonds Cem., Juniata Co., PA.
ii. Geraldine Zeiders, b. ca 1909, 1930 census; nurse University of Pennsylvania Hospital, Philadelphia, m. Sumner Danforth.
iiii. Dorothy Zeiders
Glad to see that GenForum has finally got the Zeiders name up and running. I descend from George Zeiders b. ca 1797 & Margaret Fitting b. 1793 who I believe are the g.g.grandparents of your Geraldine.
