In the Philadelphia area, has anyone ever seen tombstones for Charles Ricker & Lena Ricker, both born in Germany in 1851, died in Phila. sometime after 1910? Also, Albert Ricker their son who was born in Phila. on Aug. ll, 1886, died about 1920? Lena's name may have been Magdalena. The other tombstone I am searching for is for Andrew Johann, born 1878 in Phila. or NJ. Died sometime after 1933, the last time anyone saw him? This is a lifetime search. Thanks in advance for any help.
