Hi Jason! I saw your request for info on Philly area funeral homes and cemeteries. Unfortunately, online info is limited when it comes to African-American funeral homes and cemeteries. Fortunately, I live in the Philly area, so I can tell you that the Savin Funeral Home is still very much in operation(no website). I don't know how good they are about keeping records.
Savin Funeral Home
802 North 12th street
215-765-7065

For Eden Cemetery check out their website: www.edencemetery.org
Eden is historic and has many famous African-Americans buried there.

Mt. Lawn Cemetery only an address/phone listing(no website):
(610)586-8220, 84th street and Hook Road
Mt. Lawn Cemetery had several really bad reviews written about it on the internet.

Back in the day, funeral homes did business mostly through church and cemetery affiliation. So, definitely check out Savin F.H., be sure to ask what churches and cemeteries they were affiliated with in the past. This may help narrow down info or even photos of your ggrandparent.
Good Luck!
