There is a Mary Ann Langley, b. 1869 listed as daughter in the 1870 Washington Co, MO census of Christopher and Julia nee DeClue Langley. However, Christopher Langley and Julie DeClue married in 1877 Washington Co, so does this mean Mary Ann was the previous child of Christopher OR Julia? In trying to determine if Julia was previously married (she is a few years older than Christopher), I see that Anthony DeClue and Joseph Boyer witnessed the 1877 marriage of Christopher Langley and Julie DeClue. I find Anthony listed as follows.  Is there a chance that Julia Shelton, age 23 in the 1870 census was Julia DeClue, age 3 listed in the 1850 census?
