David C. Leach was born on March 7, 1831, in New Hampshire, the son of Ira (1791-1841) and Aseneth (Crowell, 1800-1867).
Ira was probably living in Londonderry, Rockingham, New Hampshire in 1820 and in Windham, Rockingham County in 1830. He brought his family to Michigan in 1835, settling in Jackson County, near Concord, and he eventually moved to Carlton, Barry County in 1837. His family joined him in Barry County in 1839 or 1840, after he had cut a road to his farm and built a cabin.
David married Francis A. Sage (1842-1916) in 1856, and they had at least six children: Major Floris, Colonel M., Captain P. David E., Mrs. Lottie Cunningham (1862-1918) and Mrs. Clara Lamson.
In 1860 David was probably the same David Leach who was working as a cook in Jackson’s Fourth Ward, Jackson County, and was in prison on a charge of passing counterfeit money.
In any case, David stood 5’11” with blue eyes, dark hair and a light complexion and was 33 years old and probably working as a farmer in Barry, Barry County, when he enlisted in Company E on January 27, 1864, at Grand Rapids for 3 years, crediting Barry, and was mustered January 28. He joined the Regiment on March 29, was transferred to Company E, Fifth Michigan infantry upon consolidation of the Third and Fifth Michigan Regiments on June 10, 1864, and mustered out on July 5, 1865, at Jeffersonville, Indiana.
After the war David eventually returned to Michigan, settling for a time in Hastings, Barry County. By the mid-1880s he had settled in Grand Rapids, and was reportedly residing in that city in 1888 and 1890. He was living in Grand Rapids in the mid-1880s when he testified in the pension claim of George Bellows, who had also served in Company E. David resided at 59 Jefferson Street from 1906 through 1911 and was living at 519 Lexington in 1914.
In 1890 he applied for and received a pension (no. 533196), drawing $20 per month by 1914.
He was a member of the Old Third Michigan Infantry Association and a member of Grand Army of the Republic Custer post no. 5 in Grand Rapids for 26 years.
David died of “senility” on Wednesday morning, April 8, 1914, at his home at 519 Lexington Avenue, Grand Rapids, and the funeral was held at the residence at 2:00 p.m. on Friday April 10. He was buried in Fairplains cemetery: section C lot 38.
In late April of 1914 his widow applied for and received a pension (no. 785769).
