Couldn’t find a city named Sharrington or Sherrington in France. I believe there is an error in the 1851 U.K. Census. Here are some sites concerning Sharrington and Sherrington.http://en.wikipedia.org/wiki/Church_of_All_Saints,_Sharringt...http://www.visionofbritain.org.uk/place/place_page.jsp?p_id=...http://en.wikipedia.org/wiki/Sherrington

As far as I know, no French city ends with "ington". This is typically English. BUT, I could be wrong.
