Laurie: "Can anyone give me a map reference or other > information for either the hamlet of Lower Osgoodby or Witham House > or its associated farm?" You might want to try the original ordnance map for that area. Probably from the 1830s or 1840s. You can try oldmaps.com http://www.old-maps.co.uk/ or British History on-line: http://www.british-history.ac.uk/map.aspx?compid=55145 When you find the copy of the map you want you can order it from the Ordance Survey. Good Luck Michael
