Hope this is helpful:
I'm rummaging around in Rebello*, thinking there might not be a legitimate Nebraska connection. Thought I'd check wills. This is an entry in Uncle John Morse's will:
"Mrs. Amy Andrews, niece, Scotts Bluff, Nebraska children of Selecta Morse Shaw, married Philip Shaw, Jr."
Joe and Ms. Beaulieu (sp?) found reference to Nebraska while researching old news items on John Morse:
"John Morse and J. C. Anderson have returned from a trip thru Nebraska and Kansas, driving overland. The two enjoyed themselves as much as when they were boys." Glenwood Opinion, June 14, 1900: 8.
"Bordens Lived West / Lizzie Was a School Teacher and Objected to Second Marriage," New Bedford Daily Mercury, Friday, June 29, 1893: 2.
"It was erroneously reported that Lizzie lived on a farm in Glenwood Mills County, Iowa, just across the river from Omaha, Nebraska, from 1870 to 1883. It was at this time that Andrew married Abby, according to this report."
Malvern Leader, IA, June 29, 1893.
"The Nonpareil [at Council Bluffs], is authority for the statement that Lizzie Borden, who was tried and acquitted of the murder of her father and stepmother at Fall River, Mass., and whose trial created such widespread interest, was for some years a resident of Mills County, living with her parents near Glenwood. It was while living in this county that the murdered couple were married. Lizzie was a school teacher and taught in several districts near Glenwood."
--[I recall seeing the copy of this original item during Joe's research on Morse]:
Red Oak Sun, IA, June 30, 1893.
"Lizzie Borden, of Fall River, Mass., who was recently tried for the murder of her father and step-mother and declared by the jury not guilty, used to live near Glenwood and taught school in Mills County. Her father and her step-mother were married in Mills County.”
"Hastings,"' Malvern Leader, IA, July 6, 1893.
"It is said by those who are in position to know that it is a mistake in regard to Miss Lizzie Borden or her father ever living in Mills County, as published in the Council Bluffs papers. It must have been some other family of that name."
These are what I recall on Lizzie and Nebraska.
Anyone else know anything more?
