Found the following Bio sketch at eBay, thought somebody might need it. I have no further info for any Newberys.
Rev. Robert L. Newbery is a son of the late Allen T. Newbery, farmer and trader of Bland County; whose wife was Elizabeth, daughter of Robert Bogle, and a grandson of Rev. Samuel Newbery, a pioneer minister of the M.E. Church in which is now Bland county. He was born near Bland C.H., on New Years Day, 1834, and is now a farmer of the county, as well as engaged in the work of the Ministry in the M.E. Church (South) here. During the late war he was exempt from service on account of his profession, but rendered some volunteer service in Missouri, and had four brothers in service, as recorded in the sketch preceding this one. Mr. Newbery is a member of Bland Lodge, A.F. & A.M. He married in Jasper County, Missouri, on October 28, 1858, Margaret H. Hunter, who was born in Wythe County and raised in Bland county, near Mechanicsburg. Their children are four sons and three daughters, born in the order named: John Allen, Mary Elizabeth, Samuel Price, William White, Ella H., Jesse H., and Maggie C. Mrs. Newbery is a daughter of the late Moses Hunter, farmer, mechanic and mill owner, who in 1857 removed from Bland County to Jasper County, Missouri, where he died. Her mother is Elizabeth H., daughter of William Hoge, a large farmer and grazier of Pulaski County, Virginia.
