I have a request to check a marriage. I have an Agnes Elvira White, listed as widowed in 1880, aged 41. I am positive she remarried in the 1880's in Benton County. Her son, my GG granddad moved to Texas in 1906 and I have a reference from my Great-granddad about going to grandma and grandpa's mill.
She is listed differently on each census. 1860 - Alvira White; 1870 - Alvira; 1880 - Agnes E. White. After 1880, she appears to drop off the face of the planet. I do know she did not move to Texas with her children and their families.
