Farmer and Moore's Gazeteer of N.H. (1823) speaks of Otis hill as the highest in Somersworth, about a mile above Garrison Hill. It is also mentioned in Hayward's New England Gazeteer of 1839. It is otherwise called Ricker's Hill, from the former proprietors. It is now owned for the most part by the Rollins family, and is sometimes called Capt. Ichabod's hill, or Capt. Ich's hill, from Ichabod Rollins, who first acquired a part of it Jan. 14, 1771, when Levi Ricker and his sister Judith conveyed to said Ichabod all right and title to the homestead of their honored father, George Ricker, Jr., deceased, who, it is stated in the deed, lived at Otis' Hill, so called.
