I'm actually in California, my mother, Violetta's granddaughter is living in Wiltshire, where I was brought up. :) I believe my mother found where she was buried, but couldn't find a gravestone. Apparently Violetta had a thing for cherries throughout her life, and also she was tiny, I've heard that she had to stand on an orange box to marry my gt grandfather James Thomas Coulson. I believe they eventually moved to the Wakefield area in Yorkshire. They also had three children: Samuel Frances, Helen (who died at birth or shortly thereafter) and Frank. Details for us are rather sketchy. My Grandfather died before my Mum and I started doing this research, and my Step-Granmother isn't very forthcoming with details on a number of things.
I've forwarded your message onto my mother to see if she has more information, and any you could give back would be appreciated :)
