Hi, Can you partner help with the surname? if it is his GGGrandmother - there may be some information. Does he know when? Where his GGGrandparents passed away ?
Does your partner know the given names for his GGGrandmother GGGrandfather
Search of Census 1901/06/11/16 may find a correct spelling for a given name.
Is there information about the GGrandparents/ Grandparents - with the same surname ?
Family members may have submitted family history/stories to a local history book project.
There may be others for the area - a google search found the following
