Col. James Mason was born in Culpeper County, Virginia, September 29, 1769, the son of John Mason, September 1, 1743, Spotsylvania County, Virginia, – April 11, 1831, Fayette County, Kentucky, and Anna Marie Murray, January 2, 1741 – December 19, 1819. 

James Mason married Anna Elizabeth Fishback January 7, 1799, in Clark County, Kentucky.  She was the daughter of Jacob Fishback April 14, 1749, Culpeper County, Virginia – September 15, 1821, Clark County, Kentucky, and Phoebe Morgan, September 15, 1751 – August 16, 1837.  The minister was Ambrose Dudley and he only recorded the year for this marriage.  Perhaps he thought he had a better memory than he actually did.  Thankfully it was added to her gravestone.

James and Elizabeth moved to Montgomery County where they raised their family of nine children:

1. Ann Shirley Mason, June 12, 1800 – November 27, 1883, Fayette County, married Samuel Grant Jackson, October 19, 1800 – December 11, 1853, buried in the Lexington Cemetery.
2. John Calvin Mason, August 4, 1802 – August 4, 1865, died in Louisiana, buried in Frankfort Cemetery, married Ann E. Owings June 6, 1847.
3. Peter Bainum Mason, March 4, 1804 – April 18, 1870, died in Boyle County, buried in Bellevue Cemetery, married 1^st Sarah Woods Carpenter, 1811-1848, 2^nd Elizabeth Carpenter, 1812-1852, 3^rd Arabella Dodge Holderman, 1817-1854.
4. James F. Mason, June 20, 1806 – October 18, 1873, died in Texas, married June 6, 1833, L. A. Smith.
5. Luther Mason, October 1, 1808 – March 8, 1891, died Jackson County, Missouri, married Martha Moore Price, August 12, 1820 – March 7, 1877.
6. Caroline Mason, April 22, 1818 – May 17, 1882, died in Clark County, married a Samuel Wheeler.
7. Lewis Lunsford Mason, May 16, 1812 – March 7, 1877, died in Arkansas.
8. Anna Maria Mason, 1824-1863.
9. Catherine Chew Mason, 1828-?

In the 1850 census of Clark County James Mason, widower, lived with his son-in-law Samuel Wheeler.  Samuel was 48; wife Caroline was 40.  Children in the family were Eliza A., 19; Caroline, 10; and Martha, 6.  James Mason was 80.  John Dearborn, a preacher, lived with the family.  He was 24.

Five years later James died and was buried beside his wife in Machpelah Cemetery in Mount Sterling, Montgomery County.

I found a couple of articles that mentioned Col. James Mason:

The Kentucky Gazette, Lexington, Fayette County, Kentucky

Van Buren and Richard Mentor Johnson were elected president and vice president.  Johnson served in the Kentucky House of Representatives and the U. S. House of Representatives prior to his term as vice president.

And I found one obituary – that of son Luther Mason.
