Today I found a marriage record for Robert and Georgianna in Webster County, IA. They were married 11 December 1878. Georgianna's name was given as "Georgie C.," though. I've found an awful lot of relatives who went by a name other than that given to them by their parents.
On 5 June 1880, Robert and Georgie were living in Omaha, Douglas County, NE. His daughter Bertie, who was 18, was living with them. She was born in New York State. I discovered from an 1891 directory that Robert was a manager at Mound City Paint Color Company (the company was bought by the Glidden Company in the 1950s). I don't know if Robert died in Nebraska and that is why Georgie moved back to Iowa to be near relatives.
It was not easy searching for either Georgie or Robert in Ancestry. Not many records came up at all. I didn't think those names were so difficult. Maybe in the future I will come across more information.
