Population over time

2 figures

Monroe grew from 12,442 to 15,412 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

John Reed, the grandfather of William Reed, and the ancestor of the Reed family in this neighborhood, cut his way through from Pennsylvania first to Kentucky, in 1798, settling near Crab Orchard. His wife's brother, whose name was Brotherton, was killed by the Tories in the Revolutionary War.' He remained here but a year or two, and then, with his wife and family, struck out for Cincinnati. This was in 1797, and from here he moved up the Miami, and here, three miles below Middletown, at the mouth of Dick's Creek, he located. The children were David, Robert, William, and John, Jane, Christian, Margaret, and Martha.

David Reed, the father of William Reed, was married in Pennsylvania to Miss Ruth Carricks, September 30, 1766, while yet in Pennsylvania. Her people were from the north of Ireland. Their son John, their oldest child, was born in 1794, when they went to Kentucky on horseback. They brought some fine horses with them to Ohio, but four of these were stolen one night by - the Indians. David, Robert, and their father followed them two days, but failing to catch the thieves, Robert and the father returned home, and David continued the search singly for three days longer, and was gone five days and nights. Upon reaching the Miami River at night, on his return, having no skiff, he took off his clothing, lashed his gun, powder-horn, and clothes to his back and swam across the stream. He was not fond of the noble red man, and, it was said, would occasionally shoot them down without much provocation. He died in 1812, and left five sons and four daughters: John, Thomas, William, Robert, David, Margaret, Jane, Elizabeth, and Ruth.
