Could Phillip have been married twice? I have a record that says that Jacob Derr's mother is Harriet Henninger (1859-1886), having two children together, Alice 1879, and Jacob in 1880. Then I have a census showing Mary (1866) married to him in 1889.
Can you confirm, and if so, what are your citations? I got the first wife info from a woman named Ellie Dubritsky, on ancestry, how knows some of my husband's family and who searches courthouse documentation.
Also, I did not have your gg-grandmother as Phillip's sibling. I did have John (1850), Leonna (1852), Alice (1856), and Hettie (1864). What year was Catherine born?
Finally, do you have anything on Phillip's parents?
