I have been doing genealogy research for 30 years on the Parchman/Parchment/Perchment clans and have most names from 1750 to 1930 connected to the family. The Ohio clan descended from William Perchment (b 1830 in Pittsburgh), the son of Peter Perchment (born 1801), the son of Revolutionary soldier Peter Parchman/Perchment. All Of the descendants of the soldier took the name of Perchment, while the descendants of Peter's 2 brothers (John and Philip, who moved to Tennessee about 1789) took the name of Parchman. Peter's war records are mostly in the name of Parchman, as are some tax records. I think William left home in a huff when his father remarried, and went down the Ohio as a river as a boat joiner and settled in Cincinnati, where he was listed as a house carpenter in 1880 census. He was identified as the grandson of Mary Perchment (wife of the soldier) in her will. William's line is the only one with the Perchment name that survived past 1900, since all the other descendants left only female heirs, as there were few males, and they died young. William had 4 children by Oromina--Charles A, William, Ella, and Henry Leonard. I think that the latter William went by the name of John W Perchment, since he was the right age and appeared in the 1880 census, then as a soldier from Ohio in the Spanish American War and in the Yukon Territory in some indexes. I have a little more information if you contact me.
