Thank you, everyone, for your kind comments. I have found some information on ancestry.com and also on familysearch.org. I have been able to find his death certificate, his marriage docket, and his grave on findagrave.com.
I know the names of his parents, Philipp Schneider and Philippena Sparrenberger. They are all buried in Indian Orchard Cemetery in Honesdale, Pennsylvania, USA. He had several siblings, and I have limited information that I have been able to learn about them. All of the information about my great-grandfather and his family members is available in my public family tree at ancestry.com.
His widow (my great-grandmother) is Cora Belle Funkhouser, who was born in New Brighton, Beaver, Pennsylvania, where they married. I would love to know how they met, as New Brighton is quite some distance from White Mills. My grandmother, their only child, is Charlotte Belle Schneider Schenk. I have begun building my family tree on WikiTree, but it is only a seedling and a work in progress compared to my tree on ancestry.com, which is quite extensive.
Unfortunately, I became interested in genealogy in the autumn of my life, and there is nobody left to ask about my ancestors. The last of my grandparents passed away when I was only 14 years old, my parents and all of my aunts and uncles are deceased, and I probably know more than any of my cousins.
Thank you, again, for your kindness and any assistance that you may be able to provide.
