According to an Internet database of Illinois veterans of the Civil War, a man by the name of Marcus L Stowell was listed in Company D of the 42nd Illinois Infantry. His residence at the time of enlistment was listed as Lowell. There also was a Lafayette Stowell in Company D, but the Internet veteran site did not indicate where he resided at the time of his enlistment. Since Marcus' middle name was Lafayette, chances are that the "L. Stowell" from the 42nd Ill. Inf. on the Lowell Monument represents Marcus Lafayette Stowell.
Gerald Born, a descendant, writes:
Myron Stowell had three brothers who also served during the Civil War. They
were John, Lewis, and Marcus. I think a couple of them enlisted at
Kankakee. John lived at Lowell and Lewis lived at Water Valley. Marcus
moved to Kansas shortly after the Civil War.
Their father, Loren Lorenzo
Stowell served during the War of 1812, probably from Connecticut or New
York. Loren moved to Shelby, Indiana from Kalamazoo, Michigan, after the
death of his wife in 1846. Loren was born at Stafford, Connecticut, the son
of Dr. Oliver Stowell of Pomfret, Connecticut and Abigail Strickland of New
London, and married Mary Matilda Reed, a daughter of Talcott Reed. He was
married three different times. By the second marriage he had a son, Stewart
Stowell, who lived at Shelby.
Loren died in 1872 and his obit can be found
in the Lowell Tribune. Myron died in 1911 at the Old Soldier's Home at
