James Crombie Mansur was born 16 February 1846 in Dover, Strafford County, New Hampshire, United States to Horace Mansur (1820-1900) and Abigail Titcomb Leighton (1828-1855) and died 9 December 1916 Sacramento, Sacramento County, California, United States of unspecified causes. He married Harriet Ann Crow (1848-1928) 16 February 1876 in New Castle, Placer County, California.

James arrived in California with his parents in 1852. They settled in the mining community of Horse Shoe Bar, on the North Fork of the American River, approximately 35 miles N/E of Sacramento. The area was inundated with the completion of the Folsom Dam in 1955.

James is shown in the 1900 US Federal Census as living at 316 14th St., Sacramento, CA, with his wife and three children (Horace, Mille and Benjamin). His home was located next to the train terminal. For many years, he was a conductor for the Central Pacific Railroad.

James was co-executor of his father, Horace's will in 1900 - 1905 (probate, 1902), with step-sister, Sarah, daughter of Electa (Newberry) Wixon / Mansur.

James and his wife Harriet Ann are buried in the Mansur plot in the Newcastle Cemetery, just east of a Civil War monument. Placer Co., CA. The plot has concrete curbing with "Mansur" embossed in the step. There are three, polished, red granite headstones. One is marked "Mother," another "Father" and the third shows James and Harriett's names and dates of death. Since the granite sub-structure precluded double burials, we assume the latter was a memorial stone and the Mother and Father stones mark the graves of Harriet and James, respectively. Unfortunately, the original cemetery records have been lost. There is also a cement maker for their son Horace in the plot and indications of other, unmarked graves. - D. V. Mansur, September 2002.
