I received a copy of the will of Isaac Watson who died October 1841 in Warren County, Ohio. His executors were John Carr and Harrison Watson who were a son-in-law and son. I believe Harrison is the one buried in Greenwood Cemetery in Hamilton, born April 15, 1813, died August 20, 1849. This fits with the fact that he was not mentioned in his mother's (Mary Round Watson) will of 1861. Mary listed a Mary and George Watson as heirs, probably grandchldren and I find an Elizabeth Watson with children Elizabeth and George in 1850 and 1860 in Hamilton. I would be interested as to what happened to them. Harrison Watson would be a brother to Wiliam Washington Watson, Sarah Kendall, Matilda Dunn, Juliann Carr and Elizabeth Carr, wife of John Carr
