I have grave info on a Frederick and Henry Schumaker.Frederick's middle initial is W. and is probably the son of Frederick.Could Henry's birth be 1827 instead of 1828? I have just added the Schumakers to Findagrave.com.These are the ones I have added (pictures of headstones are on findagrave.) Frederick W. 1857-1935, Henry 1827?-1901, Henry M. 1882-1937, John F. 1861-1949, John Henry F. ????-7-24-1891, Wilhelmina ????-????.Let me know if I can help any further.
