Our family ancestor Sarah Ann Ray, married James Melton in 1866. Her obituary says she was born in 1847 in Missouri. I believe she is the Sarah Ray in the Moses B Ray Family. Family Legend (I can't prove it) is that her Mother's name was Rachel. I have been trying to fit here as the Sarah in the B. W. Ray (Wife also Rachel) found in the 1870 Census of Pettis Township, Platte County, but that Sarah was unmarried in 1870.
The Moses B Ray's daughter, Sarah, is a good fit. I believe B W Ray and Moses Ray are two separate individuals who coincidently married women named Rachel, each born in 1819.
