Shearer Souder Family

My name is Ted S. Shearer III. My grandmother's maiden name was Estella (Stella) Souder. Her father was John F. Souder and her mother was Sarah Ann (Bilger) Souder. Joh was first married to Agnes Detweiler before she passed away thre children resulted in that union:Archer(1873),Mary Ellen and Charlotta Souder Stover. What I am trying to findout when John and my great grandmother,Sarah Ann, did in Phila. I know the both where in Phila in 1920. I also can't find anything after the 1880 Franconia Census about Archer. Thank you for any help.
