Lindauer received his first Masonic degree on March 23, 1861 and his second on April 3, 1861, and completed his membership on January 27, 1864.
Tom Savini of the Livingston Masonic Library noted that Lindauer may have served in the American Civil War, since "it is not usual to have a three-year gap between the 2nd and 3rd degrees.
Testimony involving Charles was: "Lindauer has a new place [in New York City]; he is a small fry backer.
"[citation needed] In February 1857, Charles married Anna Augusta Kershaw (1841–1931), most likely in New York City.
They had six children: Eloise (1861–1935), William (1866-c.1870), Adeline (1862-before 1921), Anna Lillian (1872–1956), Harry Chauncey (1877–1923), and LeBaron "Lee" Hart (1879–1945).
