Loren & Mary Taintor* (by attorney)
Benton County, Missouri
Jacob and William Loree of Lapeer
Loren & Mary Tainter bought land in Section 11 of Handy Township, Livingston Co., Michigan, before moving from their home in Livingston County, New York, but apparently were never residents of Livingston Co., Michigan. However those land patents (see links) from the Bureau of Land Management (GLO) issued to Loren and to Mary are proof that they once lived in Livingston Co., NY.
More about Loren Tainter and his ancestors can be found here in "A history and genealogy of the descendants of Joseph Taynter: who sailed...." By Dean Willis Taintor.
Loren Tainter and his descendants can be found here in "Francis Hatch & primarily Loren Tainter family histories." Members of the Tainter family moved from Missouri to Minnesota because of the difficulties of the Civil War in Missouri. The publication linked above has lots of information about the family in Minnesota.
