Bowers In PA. From Germany

I am looking for any information regarding the Bowers family in Philadelphia, PA, especially death information. The only info I have are the 1900, 1910, and 1920 PA census. I would especially like information before 1900, and any immigration records. William Bowers was born about 1857-60 in Germany, immigrated to the US around 1883. His wife Elizabeth (Kramer)born in Germany about 1876, and immigrated to the US around 1885. William and Elizabeth married in the US, I believe. They had 5 children...William Jr., Wilhelmina (Minnie), Joseph, Margaret, and Elizabeth. If you have ANY information...Please email me at passionforthepastgenealogy@yahoo.com Thank you so much! ~Pattie~ :)
