Chuck - it sounds like you must have a copy of the old family history by cousin Betty Boyd THOMAS who married Henry Tarriman WARDER. She sent copies to my grandmother early in the 20th century. I have those copies, but I have never proven that connection to the MATHEWS family. I also have not proven the "marriage" of Dorothy MATTHEWS to John MILLER. I have researched Buckner MATHEWS and Dorothy BUCKNER and never found proof of their marriage or a child. If you have documentary evidence, I would LOVE to hear from you about it. I have considerable evidence on the children of John MILLER (no wife's name in any of the wills or deeds I have found). I did find another Dorothy MATHEWS who married Thomas MILLER, who is apparently not kin to our MILLERS.
My line goes from Robert MILLER and Cassandria MOORE, daughter of Col James Francis MOORE of Jefferson Co. Their son, James Francis "Frank" MILLER married Mildred Ann CAMP (his brother, Anthony, married Mildred's sister, Ellen CAMP). I descend from James Francis MILLER, Jr, who married (1) Marinda McCARTY and (2) Martha Ann GRAY (dau of Gideon GRAY and Judith Ann ROBINSON of Hardin and Meade Counties, KY. My grandmother was the youngest child of J F Jr and Martha Ann Gray.
Hope to hear from you.
