There are 8 Elizabeth deaths recorded on the carlisle history page, or I suppose she could have remarried.
The Carlisle pages only include burials for which a stone exists, as the site owner offers to sell photographs/MIs.  The ages are easily found from FreeBMD.

You say James died 5 Feb 1909.  He is commemorated on stone 15/18 ... along with 5 other ROUTLEDGEs.  Perhaps their dates my be of use to you.  Elizabeth doesn't appear on that stone.
