Berb hi I have a Mary Frances Crenshaw in may tree but my search has not having a husband. She was born September 2, 1849, in Lincoln County, Missouri. World Family Tree has a time frame her death between 1877 and 1943. Her father was Joel Nelson Crenshaw, born October 3, 1802, in Bullitt County, Kentucky, and died February 23, 1893, in Lincoln County, Missouri. His spouse is unknown, but they was married February 23, 1832, in Lincoln County, Missouri. Beside Mary France Crenshaw, there was 14 other sibling. I don't if this Mary Frances Crenshaw is your or not. For Ferguson is also one of the surname that come in my family three. The Ferguson's through Missouri and possible Arkansas,in their move from what is now West Virginia to Oregon. Ihope that this bite of information is helpful to you, if I am sorry I tried to be helpful.
