My great great grandfather was William Mead(e) who was born c. 1820 in Kentucky. He married Elizabeth Johnston Aug. 8, 1841 in Floyd Co., KY. Their 1st 4 children were born in KY between 1844/1851. They had moved to Missouri by the birth of their next child in 1856. Any information on William and/or his wife would be very much appreciated. Thanks!!
