Was Daniel Spangler and Michael Spengler brothers?

Missouri Census 1840. Spangler, Jacob (County) Barr(y) (Houshold?) 021 (TWP) Spring R(iver) 2 male 40-50
1 Female 30-40 2 Males Under 5
Missouri Census 1850 Jacob Spangler not found
Missouri Census 1860 Barry County Jacob Spangler not found
Children: (This is a guess based on the Barry County MO Census 1840 and Coffee County, TN Census 1860)
(1) Jacob Westley (abt 1835-____)
(2) Isaac Henderson (abt 1839-____)
It also appears that Lydia married J. R. Vernor and had two more children born between 1840 and 1844 when she
died in Tennessee. Did Jacob die in Missouri after the 1840 Census and Lydia return with the children to Tennessee
where her mother, a brother and 4 sisters still lived?
Is the 120 acres in Barry County, Missouri mention in J.R Vernor's will the land once owned by Jacob Spangler?
This proceeds from the sale of this land was to be divided equally among Lydia's four children and J. R. Vernor's
children (probably by a previous marriage) were not included in the proceeds from the sale of this land. From these
facts I suspect Jacob had died in Missouri after the 1840 census was taken and before 1843.
