Easy, dear lady. My general goal was to point out that this gentlemen could well be a Forrest descendant of the General's but obviously, you are quite correct, not a direct male descendant. As for his volume of research, I suspect you are well on target.
Curently I have found the following:
William Montgomery Forrest [ Nathan Bedford, William, Shadrack, William, James] Captain Forrest was with his father Nathan Bedford Forrest in all the campaigns that caused the world to ring with his fame. He was wounded three times, at Fort Donelson, at Harrisburg and at Spring Hill, Tenn. At Harrisburg, MS on 14 Jul 1864 as a Lt. Willie was thrown from his horse by a concussion from a shell and was carried from the field. He was paroled at Gainesville, Alabama May 11, 1865. William married Jane Taylor Cook 1868 in Hernando, DeSoto County, Mississippi. He joined the Historical Society in Memphis, Tenn. Oct. 9, 1904. He died Feb. 8, 1908 at his home at 187 Adams Avenue,. Memphis, Tenn. He was stricken with a fatal stroke of paralysis while at the Lyceum Theater. His funeral was held at the Court Avenue Presbyterian Church, Memphis, Tenn. It is written that he had a premonition of his death, as he wrote in a letter to his wife Jane on the night he collapsed with a stroke.
Children of William Montgomery Forrest and Jane Taylor Cook are:
Mary Elina Forrest b. 12 Aug 1869 Oxford, Lafayette County, Mississippi d. 22 Oct 1965, buried in Elmwood Cemetery, Memphis m. Thomas Jefferson/Jessie Bradley 1892 (see family later)
Nathan Bedford Forrest II b. Aug 1871 m. Mattie Patton 1904
James Cook Forrest b. 1872 d. 5 Mar 1881
William Montgomery Forrest Jr. b. 21 Mar 1874 in Memphis
