Dear Sue
It is nice to hear from you all the way from Michigan! apologies for the delay in getting back to you.
You may have read in earlier posts that I am Guido Devoti's grandaughter. I have been speaking with my Uncle, Peter (Guido's son) to check on the information you are looking for.
The information you have posted is all accurate, however I can clarify that Maria Devote Oliva is not related to Guido Devoti. It is just a coincidence that the names are so very similar. We are unsure as to the exact spelling of your Maria's surname (whether this is Devote or Divote) but my uncle is aware that there was a family in the Northwest with this name in the late 60's/early 70's as a man with this name introduced himself to my grandad Guido at an Italian convention - the discussion focusing on the similarity in their names! I do hope that this is of some help to you.
As you say however, we are distant cousins via the Granelli's!
Both the Granelli's and the Devotis came from Santa Maria Del Taro which is on the mountain pass behind Lavagna. If you look at earlier posts on this sight you will see a picture of the village.
I believe that it was your relative in the UK who met quite recently with my family.
Good luck with your searching, please let me know if we can be of any further help.
Kind regards Julia
