If you’re looking for McConnel Island in Idaho, you’ll have to dig a little deeper. Ask around when you’re in Parma.
In the early days of settlement in that area the Boise River formed a delta, with two channels, one to the north and one to the south, forming a 4000-acre island. In 1865, David McConnel claimed land on the island and built a home there as a squatter. In 1879 he applied for and received a homestead claim of an additional 160 acres, bringing his ranch to about 500 acres. Other families, including that of David’s brother, Ben, lived there, and it even had a McConnel Island School.
David McConnel had come West in 1862 with a large Oregon Trail wagon train. He acted as a scout for that train. McConnel had 11 siblings, 10 brothers and a sister. Eight of his brothers followed him to the Boise Valley from their home in Iowa.
McConnel was a vigilante. That word has a negative note to it today, but it was a point of pride for him. It was the beginning of law and order in the area. In writing about his grandfather, Carl Isenberg recalled McConnel saying that “until the committee was formed and operated on several of the rustlers, murderers, etc., no one could feel secure, but that after a few examples, property and individual safety was secure.”
The island became McConnel Island because of David McConnel’s association with it. It ceased being an island when the Ross Fill was built to block off the southern channel of the river to help solve a frequent flooding problem.
