I'm sorry Philip but the dates are wrong for the difference between our 2 Mary Ann Smiths.
I happen to know that mine is correct - I visited Gunwalloe Church and graveyard and I was puzzled to see
a Plomer next to her sister. Following that lead led me to accept the leads. She was the sister-in-law of Dr George Appleton
and she was living with them at Parc Brawse at the time of her death.
Feel free to have a dip into the Plomers in my tree - fascinating bit of history.
Best wishes
Janet
