Michael Yankey had a brother, Jacob, Sr. who married Mary Sturm and moved to Kentucky. This is your line I believe.Contact me email@example.com.My family was in Missouri for some time as other family members were already there.I believe that your family was there.I do have considerable Yankey/Yankee information.I have information that Jacob,Jr. and Ruth were in Flat Creek Township, Pettis County, Missouri in 1840.I do not have much about your family line so would like to share.
