I've run into the same problem in Lafayette County and it's not just Ancestry.com that is missing the data-genealogy.com does not have it nor does HeritageQuest(I think Genealogy.com uses the HeritageQuest data anyway). I cannot find any of my Browns in Lafayette County around Mayo. I know they were there. I can understand maybe one family being missed but there were several familes and none show up. I'm hoping the library will have a copy.
