Does anyone have any info on a Mary Harris, a possible daughter of Elijah and Sarah Matthews Harris. She was born between 1813 and 1815. She married Wm. Haynes Blue on Apr 16, 1835 in Knox County.Both Elijah and Sarah and Wm. and Mary show up on the 1850 in Jackson/Clay twp area of Knox Co.(Bladensburg)I have 10 children for Elijah and Sarah but not a Mary. According to a Blue family genealogy site, Mary's father name was Elijah Harris but no mother's name is listed.Wondering if this could be another child of Elijah and Sarah since location and timing are logical. William and Mary moved to Greene County, Indiana between the 1850 and 1860 census.Both died and are buried in IN.
