Looking for death certificate for Joseph Hunt Mercer, born 1860. He was son of Michael Jones Mercer.

I have documented that he married Havannah Frank in 1881 and Susan E. Hunter in 1891. (he is referenced as Joe H. Mercer in 1891 marriage record).

Looking for birth certificate for Joseph Otto Mercer(my grandfather)B.3/3/1884 d. 9/3/1956
John Otto Mercer is listed as son of Michael Jones Mercer and Sarah Davis Mercer in several family trees.

This is incorrect. Sarah died in 1883 and John Otto Mercer is listed as listed as the nephew of John E. Mercer, son of Michael and Sarah in the 1900 census records.

Any information would be of tremendous help.
