Who were Mary Ann Lobb's parents? I have Robert George Lobb 1813 whose 3 sons went to the USA. Claude Lobb went to Pen Argyl PA he became a slate splitter manufacturer... Also there is a William Lobb who owned the Dark Blue Roofing Slate company in Pen Agryl PA. Wish I could find some related Lobb's who still live in the Delabole, St Teath, Tintagel area.
