Yes their surnames would have been Kelly they were very young, as I was told my grandmother was Catholic but do remember all of this is hear say except finding them in the 1930 Census, after which on the birth records of the other children they were listed as 2 died. Okay their parents were Frederick Banks Kelly, and mother Annetta Goldie (Crumbaugh) grandparents on Frederick's side were David and Leona (Leonie) Kelly, mother's side would have been Crumbaugh. Hope this helps. 2 and 4 years I'm assuming. Thank you Cecile cecile/sis
