The Records and Diary of Isaac McComas -

an early Yuba County pioneer

These records have been generously shared by Charles McComas Robb, who is Isaac's great-great-grandson.  Charles has transcribed the following original documents in hopes that it may help other Yuba County researchers.  Isaac came from Maryland to Yuba County in 1854 - returning to Maryland 12 years later - then coming back for a time in the early 1870's..  He was a brickmaker who lived in Marysville - the first time - from 1854 through 1866.  He kept a daily diary all of his life.  The following are diary entries, and other information, spanning those years.

If you are descended from Isaac or Jacob (his brother) McComas, please feel free to contact Charles.  He is willing to share the vast amounts of research he has done, as well as photos and family letters.

Note:  Family oral history had said that Isaac stayed in Marysville until 1866.  In fact, he left to return to Baltimore in June of 1865.  However, he receives mail and does business back and forth for several years.  He made two trips to "settle affares". 

Note:  As of 1869, Isaac still has financial interests in Marysville.  As of 1869, he and his brother, Jacob, have purchased a large milling operation in Maryland.  During certain periods when "times are hard", Isaac sells some of his Marysville gold out of necessity.
