Moses S. Newman was born on January 1 or 18, 1821, in Lima, Livingston County or in Orleans County, New York, the son of Joel (born 1794 in New York, died 1865 in Plymouth, Wayne County) and Hannah Lyon (born 1794 in Massachusetts, died 1853 in Plymouth, Wayne County). Joel brought his family from New York to Michigan sometime before 1830, eventually settling in Plymouth, Wayne County where Moses was living in 1834 and 1840.
Moses married Vermonter Charlotte Cook (1825-1864) on August 14, 1844 in Clinton County, and by 1850 they were living in Plymouth next door to Joel and Hannah. (Joel died in Plymouth, Wayne County in 1865.)
Moses was 43 years old and possibly a farmer living in Riley, Clinton County, Michigan, when he enlisted in Company G on January 4, 1864, at Corunna, Shiawassee County for 3 years, crediting Riley, and was mustered on January 12. (He may have been related to Artemas Newman who was from Ingham County and had enlisted in Company G in 1861.)
Moses was transferred to Company F, 5th Michigan Infantry upon consolidation of the 3rd and 5th Michigan Regiments on June 10, 1864, and was reported in the Regimental Quartermaster department from December through February of 1865. He was mustered out on July 5, 1865, at Jeffersonville, Indiana.
After the war Moses may have returned to Michigan.
By the summer of 1880 he was a widower working as a farm hand for Nancy Myers in District 3, Dickson County, Tennessee. That same year he was probably still living in Dickson County, Tennessee, where he married a widow, Pennsylvania native Harriet Glendenning Neff on December 29. Moses may have returned to Michigan sometime in the early 1880s and was possibly living in Dewitt in 1884 (Artemas Newman was living in Dewitt in 1890 and 1894).
By 1890 he was still living in Dickson County, Tennessee.
In 1885 Moses applied for and received a pension (no. 454828). He may have been a member of the Old 3rd Michigan Infantry Association.
Harriet was residing in Tennessee in 1898 when she applied for a pension (no. 682259), but the certificate was never granted.
