8.  Christian STRAUBE, Jr., b. 1829/30; d. Mar 1850, Audrain Co., MO; bur. Fields-Fike Cem.

Isabella must be fibbing about her age in the 1850 census because she surely didn't marry Joseph FLOOD at age 14.  Mary's age in 1850 may be incorrect, too, because in the 1840 census, she was born 1820-25.

STRAWBERRY is an extremely rare variant of STRAUBE (which is pronouned in two syllables, not one).  In fact, the only other place I've seen STRAWBERRY used is by Christian's mother, when she remarried after the death of Christian's father.

Some of the children are tallied in the wrong age classes, but there can be no doubt these are our subjects.
