He may have been a cooper, (Pennsylvania Archives, 3rd Ser., Vol XIV, 425, Provincial Tax, 1774, Roxborough Township) but it is difficult to distinguish the Peter Righters. There was no Peter Righter with 26 acres of land on the Tax Assessors' List for Roxborough Township in the Municipal Archives, probably because he seems to have sold his share of his father's land to his brother Michael, although no record of the sale was found, but Peter's land was part of the area owned by Michael as shown on the map made by John Hills in 1809. 24 Sep 1799, letters of administration were granted to Michael Righter on the estate of Peter Righter, dec'd. Charles Bower of Roxbury, cooper, and John Righter, of same place, farmer, were sureties for the 300 pound bond. (Administration Book K, 15 #294 of 1799) As Michael and John were his brothers, and Charles Bower's daughter was Michael's wife, this Peter Righter was probably Michael's son. In that case it may be that the Peter Righter on the tax assessors' list for Roxborough Township for several years, as owner of 11/2 acres and dwelling, and described in 1788 as a "fisherman" was Michael's son, for in 1800 the entry changes to Peter Righter, est. There is however, a possibility that this entry may relate to Peter's son Peter, because he inherited one half of his father's shad fishery. The census of 1790 lists 2 "Riters" named Peter in Roxborough Township. One of them is certainly Bartholomew's son Peter. The other may be either Peter's son or Michael's (Heads of Families: First Census of the United States 1790, Pennsylvania, Roxborough Township 207, 208) The spellilng "Riter" was used in this census record although all the Roxborough family used "Righter". Without information about their families, no correlation of the data in the 1790 census with Peter Righters can be made.
