Hi all
Thanks for all these suggestions. Dillingcombe and Dillingcourte were both names I had thought of, although I had originally been leaning more towards Dillingcombe.
Now that there are two options I'll see if I can find anyone else with name Dillingcourte or Dillingcombe in the same area at that time.
At least I can give the lady a surname on my tree even if nothing else.
Many Thanks
Matt
