Toledo Chronicle, Toledo, Iowa, 25 Jun 1936 J. B. M. Bishop, Former Resident of Toledo, Dead - Funeral and Burial on Sunday at Oakdale, California
J. B. M. Bishop, 90, of Oakdale, California, former resident of Toledo and who since 1911 has made his home in Califor nia, died Friday afternoon. He and his son, George, and daughters, Agnes, Ruth and Janet, were spending a week's vacation at Sequoia National Park, and on last Thursday morning he suffered a paralytic stroke, causing his death.
The funeral service was held Sunday afternoon at the Methodist church of Oakdale, of which he was a member. Burial was at Oakdale. John Brown Magruder Bishop, son of Jonathan S. and Mary McGahan Bishop, was born in Logan county, Ohio, on June 23, 1845. The same year his family moved to Michigan, where his father practiced his trade of wheelwright and ran a sawmill.
In 1855 they traveled west with ox teams, settling in Tama county in Crystal township. They lived in their wagon until plowing was done, and lumber hauled from Muscatine to build their house. John attended district school in Crystal township and high school in Toledo.
In 1862, to prevent John's enlistment at such an early age, his father enlisted in Company F, 28th Vol. Inf. He died at Transylvania Landing, Mississippi, in September, 1863, and later in that year John enlisted in the same company. He reached the front in time to participate in the disastrous Red River expedition in Louisiana, and later in that year the company went by boat to Washington, D. C. where with other troups they were reviewed by President Lincoln. They joined Sheridan in the Shenandoah Valley campaign, and at the first general engagement at Winchester, Virginia, on September 19, 1864, Mr. Bishop was severely wounded in the left thigh. He did not again rejoin his command, but was discharged in May, 1865, from the hospital in Philadelphia. Returning home and finding himself incapacitated for manual labor, he decided that a further education was necessary and worked his way through Iowa college at Grinnell, graduating in 1871. Held Important Positions Following his graduation he engaged for a time in teaching, and at different times was in the abstract and insurance business. He served for six years as county recorder.
October 18, 1877, he was united in marriage with Alice Ermina Loughridge, and to them were born one son and five daughters. They lived in Toledo and vicinity until 1911, when they moved to Colorado and later to Oakdale, Calfornia. There they spent their declining years happily, though they missed the friends and associations of early days. They kept in touch with the old home through news in the Chronicle and letters from many friends.
Mrs. Bishop died in October, 1935. Surviving are the six children, George and Agnes Bishop, of Oakland, Mrs. Edith Irwin, of Salinas, and Mrs. Emily Rodden, Mrs. Ruth Wenning, and Janet Bishop, of Oakdale, California.
