I'm looking for information about Reverend Pierre Robert of St. Imier, Switzerland, who was an ancestor of my great-grandmother Eliza ("Elise") Jackson of Louisiana and a coat-of-arms that bears the name Pierre Robert and a Welsh motto -- Calon wrath Colon Dow a Digon. I have reason to believe the motto was misspelled or miscopied at some point, and that the correct spelling may be Calon wrth Galon Duw a Digon (meaning "Heart to Heart God is Enough" or something close to that.
I'm trying to figure out the origins of the coat of arms and whether it is legitimate, as well as why it would bear a Welsh motto if there was not some family connection to Wales. Can you or anyone provide more information, or an image of a Pierre Robert coat of arms passed down in your family. Especially interested in ancestors of Rev. Pierre Robert. My research shows he came to South Carolina in 1686 as a Huguenot minister fleeing persecution in France and/or Switzerland and that he helped found a settlement on the Santee River 60 miles above what was then known as Charles Town. The settlement was known as French Santee as opposed to another nearby known as English Santee.
