I am looking for information about my great-grandmother, Margaret Mumby. She married Emmanuel Richardson, b. June 2, 1880, d. May 1, 1954. I know that she was born in Swanton, Saline Co., NE and died in Everett, WA. I believe the names of her parents to be John Foster Mumby and Elizabeth Rebecca Ford. She had a sister named Martha, who married Hannibal Fayette Sutton, both from Nebraska. Margaret also had brothers named Tom and Charlie. There may have been more children. Any information regarding Margaret or her parents would be greatly appreciated. Thank you.
