I do not know if there are any traces of the Thayer Grist Mill on the Uwharrie River east of Eldorado.That mill was apparently first owned by Titus Coggins and later changed to the Thayers Mill.My grandfather Nereus Mendenhall Thayer drew a map in1910 of that area of Montgomery Co. enclosed by the Uwharrie and Baden Rivers.The map is in the NC Archives and indicates that there were several roads leading to the mill at that time.The current Forest Service map of the Badin Quadrangle shows only an unimproved 4 wheel drive road leading from Eldorado to the area where the mill was located.I have never seen this mill.
You ask about Ira J.Futrell, Rebecca J. Futrell and Eliz Futrel.Eliza Saunders Futrel (1824 - 1915) was the wife of Benager Futrel (1818 -1843).They were married in 1837 in Randolph Co.Their daughter Martha Elizabeth Futrel (1842-1914) married Milton Worth THAYER (1848-1919) in 1867.Wyatt Nance Thayer (1816-1885) of Ophir had three sons: Kindrick (1840-1863), Nereus Mendenhall (1845-1934), and Milton Worth.
Eliza Saunders Futrel married a Martin Shaw in 1853.They had at least two children John Shaw (1853-1936) and Marion Shaw (1859 - ?).Martin Shaw may have been killed in the Civil War.Eliza, John and Marion were listed under the name Shaw in the 1860 census.In the 1870 census Eliza lists her name as Futrel.Marion is listed as Shaw; I have not located John Shaw in a 1870 census.I believe that Ira J. Futrell is the son of Eliza Saunders Futrel Shaw.Ira Futrel married Rebecca Jane DAVIS in 1874.In the 1880 census Ira Futrel and Rebecca are listed living in Ophir, Montgomery Co., NC.Eliza is listed as grandmother in the 1910 census with Roby Futrell the son of Ira.
Marion Shaw was born in 1858-9 as was your ancestor Marion Elsie FUTRELLE.I have not been able to locate Marion Shaw after 1870 and he may have died, but there is the nagging question was he Marion Elsie FUTRELLE?Do you have any information on the ancestry of Marion Elsie Futrelle?
