Located the marriage record of my maternal 3rd-great grandmother, Mary Ellen (Swafford) Davis to her second husband, Robert F. Gilliland in Owen County, Indiana while searching at FamilySearch. Prior to this find, I had thought they were married in neighboring Monroe County.
Mary was the daughter of Peter Kirkpatrick and Mary Ann (Crockett) Swafford. Robert was the son of William John and Margaret Ann (Wilson) Gilliland. Both had been previously married. Robert was previously married to Sarah Kellar in 1879 in Monroe County, Indiana. Mary was previously married to James Austin Davis in 1873 in Monroe County, Indiana. Both of these earlier marriages ended in divorce, though I've not yet discovered the records.
I'm not aware of any children that Robert had with Sarah Kellar, but Mary and James Austin Davis had two daughters, Ida (b. 1874) and Delia (b.1877). Together, Robert and Mary had two children, William Everett Gillilland (b. 1885) and Mary Florence Gilliland (b. 1887).
Later, Robert and Mary helped raise the orphaned daughters of Ida, Pansy and June (my great-grandmother).
