William and Margaret (Art) Woolums of Highland County, Ohio
Oliver Harris of New Market Township, Highland County, Ohio kept a diary during the early 1800's and there are two entrieswhich apparently reference William and Margaret (Art) Woolums. On February 27, 1831 he writes that he attended the funeral service of Mrs. Woolums and on July 7, 1831, he writes that William Woolums drowned in "bare run". These are the only references I have ever seen of their deaths. By process of elimination I do not think they could relate to any other person with the Woolums surname.
The diary can be read at the New Market Township genealogy website.
