This is my ggg grandfather, and his history is very mysterious. I do know that he is buried at Handley Cemetery, Fort Worth, Tarrant Co.
Any information would be wonderful.

I am not related; I found a Milton Moore in the 1880 census in Precinct 3, Tarrant County.

I found this Milton Moore in Cole Co MO 1850 census with his parents John Moore of Maryland and Jane unknown Moore of NC. Milton married Margaret Ann Henley in Cole Co MO 02 Sept 1852. I find this Milton Moore alive in 1900 and died in Tarrant Co 21 Feb 1914 and is buried in Bedford, born NC 18 Feb 1828, mother's maiden name Henry ?

This Milton Moore's children were John M, William, Matilda J, Nancy Elizabeth, Milton Harvey and Jesse S. William Moore died after 1870 and before 1900. First 4 were born in MO, Milton Harvey and Jesse in TX.

Who was your Milton's wife and children ?
