I, too, have a great-grandparent who may have been a part of Quandrill's Raiders. My great-grandfather, John Moore, left Missouri to live in Texas. The name John Moore was an allias. He and his brother were wanted for murder in Missouri. It has been passed down that his real last name was Tucker. I searched "Quantrill's Raiders" on the net and found a list of their members. There were 2 brothers named Tucker. If anyone knows anything about the Raiders, I, too, would appreciate help.
