Francis Belle Bollenbach (1872-dau. of John)

I am desperately trying to find Bollenbachs that have John Bollenbach (wife unknown) who was father of George, Joe and Francis. Francis Belle (1872-1961) married my gr.grandfather Doctor Franklin Pyle and had 10 children with him. This is all of the information I have re: Bollenbachs. Any and all help will be greatly appreciated! Thanks,
June
