Don't know if this helps but my "Timbeys" turned out to have been "Temby" once upon a time & in only one generation moved from one end of England - Cornwall - to the other - Co. Durham. There is a Mary HOLMAN TEMBY in Crowan, Cornwall on IGI; christening 18 July 1829 - her parents were Christopher & Grace Temby. She was the eldest daughter by the looks of things so maybe her mother's maiden name was Holman. Maybe your ancestors were from Cornwall, originally?
