I'm researching the Luttrell side and am trying to locate more information on the children of Millard F. and Nancy (Luttrell) Butler who married April 21, 1881 in Hickory County, Missouri. I can't find the children or their mother on the 1910-1930 census records - what happened to them?

1. Henry Wesley Butler, born August 05, 1884 in Hickory County, Missouri.
2. Harvey Butler, born April 1891 in Hickory County, Missouri (May have been fathered by a Stout).

It appears that Millard Butler left Nancy around 1888 and married Jeline Minnie Browning, started a new family and ultimately moved to Oklahoma. I'm trying to find out what happened to the family he left behind. Any help is greatly appreciated.
