Hi Michael, my maiden name is Tonge and my family ancestry traces through the north west of England (mainly Lancashire and Cheshire) and some of the north east. I have traced a number of my ancestors back to this area as far back as the 1700s. There is a Tonge Moor and a Tonge Road somewhere in the north of England. I'm still researching but I was told the name Tonge traces back to the Vikings and that it originated from either Norway or Denmark. Given that the Vikings did invade England from the north, this story makes a lot more sense than your story about Chinese and Caribbean ancestry. Kind regards. Susan
