I noticed someone responded to you and said that Dade County may have been a part of Lawrence.Dade County was formed in 1841 from Polk and Cedar Counties. The first land deed was to my GGGreat uncle.I live in South Korea but try to do research as often as possible.I am in Dade County ever six months.Next summer I will be there for a week.Email me in late May if you need me to do some looking around.
I have a webpage if you would like to check out Dade County history.Go to dadecountymissouri.20m.com if you are interested.
I have no connection to Pidcock, however, when I am doing research, if I notice an unusual name I check to see if I can help someone out.I hope this information will help you and others.I have contacted Dorothy Anderson-York about getting a copy of her books but they are not longer available.I have excerpts for my family and yours is on one of those pages.
