A special thank you to “Anonymous” who left a flower note on Mar. 4, 2013 on Andrew J Robert’s Find a Grave Record see #28917061. "Andrew J was born 1866...son of Wesley and Ruthy Roberts...1st wife N J Drewry married Jan 24, 1892 in Searcy County, Arkansas and 2nd wife Maria Frances Drewry married Oct 28, 1894 in Searcy County, Arkansas". I did not know about the first marriage.
To the union of Andrew and Narcissa Jane, two children were born. One of those children, William Frank Roberts #161699818, that the Roberts family knew as Little Frank is buried in Memorial Park Cemetery in Tulsa. Thanks to Phyllis Roberts Hedrick for knowing the location of Little Frank's burial place.
1)Winifred Fountain Sullins was told by her mother-in-law, Hazel Drewry Sullins, that Narcissa died in a house fire. It may be the second child also died in the fire.
2)On my Ancestry page about Narcissa a note was placed by Brian Oliver "Narcissa burned to death in a wagon train to Oklahoma. Her husband returned to Arkansas and married her sister Mariah Frances Drewry".
From these two comments, we have a good idea that Narcissa's death was due to a very painful death of burning.

Per the flower note referenced above on Andrew's FAG record, his second marriage was to Francis Maria Drewry who is his first wife’s younger sister. To this union, two more children were born.
In the 1900 census, Francis Maria and the three children were living with Millard & Beda Drewry Blair. This was after Andrew's death. Beda and Francis Maria were younger sisters of Narcissa Jane. This was family taking care of family, and that was and is truly a blessing.

I don't know if there is a monument for Narcissa in the Witts Springs cemetery. My grandmother, Alzina Roberts Fountain, always placed flowers on the grave adjacent to A.J, but we don’t know who is buried there. Winifred Sullins is the one who went with Alzina at the decorations to decorate her families graves.

The 1860 census shows that William Drewry lived in Searcy County, Arkansas area most of his life, and his children were born in Searcy County.
