I believe that I can gather your information on your Claybrook. A descendant of Sarah Elizabeth Allen still lives in Adair County. There is actually a family cemetery called the Allen Claybrook cemetery that is on her property that I visited recently as I am a descendant of a sister of Sarah Elizabeth Allen. James and Sarah may even be buried in that cemetery as there are a handful of Claybrooks and Allen's that are. This descendant is a geneology hound and has done extensive family research of the Allen's going back several generations. If you will message me thru Ancestry I can get you her contact info. Thanks.
