Boyd Scott Remington's chart places this son in Benedict's family, but in 1850 he is apparently with Thomas & Susan, although it is difficult to read his name. The initials are L. L., anyway, and the birth year is the same.
In the 1880 Federal Census, Leverett L. & Eliza Remington, ages 33 & 35, are living in Northbridge, Worcester Co., MA. They have an 11-year-old daughter, Adaline.
