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.
