This was separated from Nottingham in 1734, and then included the
territory from Londongrove to the Octorara. About 1/3 of the present township
was included in Fagg's Manor. In 1742, John McGrew, Robert Robinson, William
Neill and others petitioned for a division of the township, which was at that time
frequently called New Londonderry. In 1754, Oxford township was taken from its
western side. In 1819 it was again divided, and the southern part called
Penn. A small part was added from Londongrove and West Marlborough in
1866. The early settlers were from Ireland, and the name is derived from
Londonderry, in Ireland.
