 The Sistersville Ferry crosses the Ohio River to the unincorporated community of Fly in Monroe County, Ohio.Sistersville was named because two sisters, Sarah Wells McCoy and Delilah Wells Grier, inherited the land underlying the town from their father, pioneer Charles Wells, in 1815 and laid out the town.Wells had settled on the sandy bottomland with his second wife, Elizabeth Prather and many of his 22 children (Sarah and Delilah were the 12th and 17th; his first wife Michal Owings had died in 1783 after giving birth to 10 children).
